if you've used references then they ought to be appropriately cited as usual, but there is no need to be adding background information.

Thank God past few days have been much more relaxed compared to the 1st semester and earlier weeks of secnd semester, i am sure everyone would agree. However, with easter break coming soon, the pressure is mounting for the May exams, which are going to be much challenging compared to semester 1 exams. with poster presentations being cancelled, that leaves us with yet another tuesday off, and that time i intend to utilise in doing the scientific report for #MB1031, which is going to be interesting :)

While siting an article from PubMed, do we site it as a Journal article or as an online resource (in which case we have to write the date it was updated on? :s)
and also, how can the information in lecture slides be referenced?
- Syeda Maham Batool
as a journal article, yes, and lectures are referenced like this: Cundliffe, E. (2010). Eukaryotic transcription & splicing. [Lecture]. BS1015. University of Leicester, School of Biological Sciences, Rattray Lecture Theatre, 22nd Oct 2010.

Thankyou so much Faaiza :) really appreciate that :)

Does anyone know the difference between synapsis and crossing over. from what I understand, synapsis is when the homologous chromosomes come together and act as a single unit and crossing over is the exchange of genetic material ?
I think you answered it yourself :). A synapsis also known as a bivalent is when the homologous pairs align together in prophase I as the spindle fibres attach to the centromeres whereas crossing over is the swapping of genetic material which occurs afterwards at the chiasma between chromatids.

for #MB1031, we are not supposed to add the table that we are aleady given, but the table that we derive (initial rate and substrate concentration) is infact derived from the table given (absorbance readings in time), then how would it make sense if we just add the rate and substrate concentration tables :s
The second week of the semester has passed relatively quickly. Looking at the score now for #BS1011 assessment, the help session was definitely worth going to! The #MB1005 and #MB1004 tutorials are quite fun as I work best in groups. However, the #MB1031 report writing is going to be quite challenging. Looking forward to the #MB1005 practical today considering that the last one was really good and well explained. Hope everyone has had a good week so far! :)
- Syeda Maham Batool
The first week of semester almost coming to end and looks like its been ages already looking at the work laod. Besides the timetable is really busy but cant complain, will have to get used to it. Today's 9-6 was really tiring. One thing however about this timetable would be quite positive in the sense that the hourly gaps in between the lectures would be useful to finish up on the notes from the lectures already done during the day so as they are still fresh in mind. The practical for #MB1005 was quite interesting, and I am unique just like everyone else :) quite literally as we learnt through the experiments and looking forward to the results of today's experiments as well as the #BS1009 from yesterday. This semester is going to be a lot more challenging compared to the last semester yet a lot more enjoyable due to exciting modules like Genes and Microbiology! Its just a matter of managing time more effictively and organising ourselves so as to met all the deadlines for the essays, presentations and reports ! Goodluck everyone !
- Syeda Maham Batool
Totally agree!...not only on this semester being extremely difficult yet interesting, but also the fact that you are very unique;-)

Is there any reference to the PAGE NUMBERS from Stryer, for Dr. Willmott's lectures? like there are in Prof. Schwabe's and Prof. Cundliffe's lecture notes?
I know this is very basic, however would be of much help if someone could recap the differences between... sigma and pi bonds, R and S, E- and Z-, and cis and trans
Within a Carbon Carbon double bond you have a sigma bond which acts like a single bond as well as a pi bond which is found above and below the sigma bond. This results in less mobility for the atoms. This links onto the orbital content we covered towards the end of #CH1070.
- Arnold Gangaidzo
Z (Zusammen=together) and Cis are similar as this is when the two largest groups are found on the same side of a double bond. I think Z is more specific as you prioritise the groups by the atomic number of the first attached atoms whereas with Cis you just look at the overall Mr of the group. E (Entgegen=Opposite) is in general the same as trans but opposite to Z and/or Cis.
- Arnold Gangaidzo
I am still confused over how to work out R and S so i am going to be revising that soon enough! But from what I remember R and S are used to differentiate between enantiomers which you can get from optical isomers. I think S is anticlockwise and R is clockwise and this depends on how the atoms/groups you prioritise are located. This only occurs in chiral molecules where you usually get...

- Arnold Gangaidzo
that is an excellent summary Arnold, thankyou :) However, in your 3rd post you mentioned "In most cases you then have a hydrogen as the lowest priority group which you draw as going 'into the paper'" , I thought it was behind plane of paper? :S
- Syeda Maham Batool
Thanks. Yes it is behind the plane of the paper. Is into the paper not the same thing??
- Arnold Gangaidzo
This article relates to our module #CH1070. It shows how the successful analysis of aldehydes, ketones, and carboxylic acids expands the MOA’s(Mars Organic Analyzer) capabilities in the detection of organic biomarker to these important classes of oxidized organic molecules.
- Syeda Maham Batool
Is there any list on blackboard for #CH1070 exam (both 25% one and the 75% one) stating all the equations we have to know/memorise (apart from in the lectures themselves) ? Would just be much more easier to visualise.
yep, thats quite usefu actuallyl, however, I was thinking of something on a bigger scale, covering the whole #CH1070. Looks like thats what I would be doing in the holidays now.
- Syeda Maham Batool
Probably going to have to make one yourself there. Scan me a copy when you do get round to it lol ;)
- Arnold Gangaidzo
There are a lot of important things I have learnt during this term, an its hard to think of ONE most important thing, so I will mention a List of things I have learnt in order of their importance to me.. : 1. A positive attitude towards any task at hand. 2.Time management/organisation 3. Importance od constructive criticism, both by peers and teachers 4. Learn from mistakes and improve, and just improve a little bit each day. It will compound.5. Speaking infront of a group of people more confidently 6. Last but not the least... I ve learnt how to relax sometimes without feeling guilty :)
- Syeda Maham Batool
I agree, I struggled with your sicth point, but I realise with a bit of relaxation I can work more efficiently afterwards!
- Lindsey Freeman
You're always positive! I'm sure you didn't learn number 1 this term :)
- Pardina Samson-Fessale
I like number 3. I really get frustrated with making the same mistake over and over again and good feedback is the only way forward.
- Arnold Gangaidzo
A very informative summary of Kreb's Cycle (Citric Acid cycle) which links in with Dr. Well's lectures in #BS1015. It describes the steps involved very precisely with the help of a detailed diagram. Must be checked !
- Syeda Maham Batool
#MB1030 presentations were nerve wrecking, yet fun, you get to learn so much in such a summarised way in so many different styles :) !
I think the order of my slides is slightly wrong in the powerpoint that i submitted in the morning :( for #MB1030. Is there any chance I could change it ?
thats what i was thinking, would it be ok to do that?
- Syeda Maham Batool
I think it's fine. You could submit the newer version but there's the risk of getting penalised for handing it in late. Maybe take your memory stick as a back up incase it won't let you rearrange the slides.
- Arnold Gangaidzo
@ Arnold: I can't see why they should penalize you. After all, the whole reason we are submitting them online is for efficiency. It's quicker if a single folder is open from where one powerpoint after the other can be opened instead of fiddling with memory sticks.
- Manni
Very logical but I wouldn't want to risk anything incase the professors decided that the deadline should have been met as stated for everyone.
- Arnold Gangaidzo
I feel kind of the same. There's one slide at the end I want to ignore now due to timing issues.
- Zainab Chaudhary
I think you have to contact the biological science office
- Khetase Chiwowa
Wouldnt it be a bit late now? I will still take in my memory stick, just in case.
- Syeda Maham Batool

Syeda ive got the same problem!! Im just going to email myself the corrected version as well as taking a memory stick, so hopefully they will allow us to use the corrected version as oppose to one we submitted via blackboard. Hopefully we wont be penalised...Good luck everyone!!
- Minelli Torosyan
oh thanks Minelli *fingers crossed* and goodluck to you all :)
- Syeda Maham Batool
For the #MB1030 Presentation, I did a referencing slide towards the end the last time. However, is it still ok to put the website end of every slide at the bottom right instead?
I only referenced pictures and at the bottom of the slide which they are on, did you reference the text as well?
- Arun Bahl
Yes I just spent over an hour referencing the text :( as well as the pictures, so i'll just leave it there now i guess. I have cited them on the slides and then done a Reference slide at the end.
- Syeda Maham Batool
That's very thorough, well done. :) I don't think you'd ever get marked down for being too careful.

High brain lactate is a hallmark of aging and caused by a shift in the lactate dehydrogenase A/B ratio — PNAS - http://www.pnas.org/content...
This article relates to the metabolism lectures by Dr. Christine Wells in #BS1015. It describes how using proton magnetic resonance spectroscopy, scientists found that brain lactate levels were increased twofold in both normally and prematurely aging mice during aging. Further research suggested high brain lactate as a hallmark of aging and found it to be caused by a shift in the lactate dehydrogenase. This article also relates to my #MB1030 presentation which relates to aging syndromes
- Syeda Maham Batool
a great article once again, keep up the feeds, good to know that your visions intact!...The article has great relevance to Dr wells lecs like you mentioned I do recommend all to have a read.

Hyper telomere recombination accelerates replicative senescence and may promote premature aging — PNAS - http://www.pnas.org/content...
This article relates to my topic of presentation for #MB1030. it describes how the scientists have discovered that T-SCE-driven premature cellular senescence may be a factor contributing to accelerated aging in Werner and Bloom syndromes. However its still a scientific assumption based on the observations and has not gained enough experimental support to make it a theory.
- Syeda Maham Batool
I was just looking through progeria, a condition in which ageing is accelerated by almost 6 times. Thus unfortunately this rare condition does not allow the patient to live past the age of 16. Great article once again syeda, I thought soem more detail on premature ageing would do justice to your chosen article...but on the whole a good piece for support with the assessed talk, perhaps...

#FridayReflection Google Reader - addiction or annoyance? How many feeds are you subscribed to on Google Reader and how often do you go there? Could you live without it?
Usually go on google reader about twice a week but I am still finding it hard to find the "relevant" articles as instructed. I wouldnt say i am addicted to it at all yet, it does get a bit annoying when you cant find what you are lookin for even though i am subscribed to 12 of them which i do understand is a small number and will definitely subscribe to more now. However i can live without it. e.g. now i am trying to find an article for bloom's and werner's syndromes since past 40 mins and no luck :S
- Syeda Maham Batool
I agree that finding the most relevant articles can be an arduos process at times, but however its not impossible...it took me 2 hours to find such a fantastic article on gene therapy last night, which is my topic for the assessed talk. This article which I will share with my peers, was worth the wait...as they say the fruit of patience is always sweeeet!...and where not finding the right article is concerned...could it be due to your vision??...great feeds though keep posting!
- Mayank Patel
I decided to share this link i came accross which i found quite amazing. it goes with the #BS1015 units of measurement as well. in this case on a universal level. its fascinating how the universe ranges from things smaller than we could ever think and bigger beyond imagination .... !
- Syeda Maham Batool
Thanks for the link. Very cool stuff. It really helps you to put the smaller scales in to perspective

for #BS1015 prcatical 4, the graph for the reciprocals, do we have to produce the line backwards until it cuts the x-axis for the value of Km??? I calculated mine using the gradient of that graph and not producing it backwards :s
From the Cover: tRNAHis guanylyltransferase (THG1), a unique 3'-5' nucleotidyl transferase, shares unexpected structural homology with canonical 5'-3' DNA polymerases [Biochemistry] - http://www.pnas.org/content...
I decided to share this article considering we got a mock test coming up on #BS1015 and this article relates to Prof.Schwabe's lectures. usually all known DNA and RNA polymerases catalyze the formation of phosphodiester bonds in a 5′ to 3′ direction only to maintain genetic information however now 3' to 5' polymerase (tRNAHis) is found. it is a member of a unique enzyme family whose members catalyze reactions 3′-5′ addition of nucleotides to nucleic acid substrates.

#FridayReflection - Bookmarking - how are you saving online resources so you can find and access them in the future when you need them?
well till now I have been just saving the links in favorites and then compiling them according to the different modules we have. so in my "uni work" folder, i have got 4 sub folders for BS1010, MB1030, BS1015 and CH1070, all the assignments, and reseach done related to those assignments are saved in there, with file names on specific areas, e.g. genomics etc. I back up my Uni Work folder on my flash drive, everytime i make changes in it, add or remove things..However, is there any other quick and convenient way to back them up aswell?? I have come accross the link for delicious.com, need to get the hang of it though.
- Syeda Maham Batool
Search On #fridayreflection for more about delicious. It is very easy to use and you could 'tag' your bookmarks with module codes just as you have been doing. I think you can import your IE bookmarks too.
