if that comes up i'll love the examiners forever.
I know! it has not yet came up in any of the papers so fingers crossed! Also an essay about protein structure relating to its function or DNA transfer or a specific enzyme Q are yet to come up!

Its not RNA Polymerase its Helicase that separates the 2 strands
Ohhhh yeah thanks! :-)

Yeah that's right...the DNA strand is acting like a template for RNA polymerase to from the comp strand which is pre mRNA

(Original post by sienna5)
RNA polymerase is a enzyme that moves along the DNA, allowing the 2 strands to separate and assembling the premRNA strand by lining up free nucleotides by the template DNA strand

RNA polymerase reaches a stop signal in DNA eventually and then mRNA production stopped and the enzyme deattaches

Is DNA ligase a enzyme that is used to anneal sticky ends with the required gene?

Am i the only one who would rather have a multiple answer paper like in the US? Wouldn't that be amazing?
I have multiple choice for the first part of my Chemistry paper. They can be nasty because sometimes they confuse you and you think it could be either of the the questions. Plus you can spend ages on working one out and it's only worth one mark so you waste time. Not cool

That would be a BLESSING seeing as I have just resat the unit 4 last week,

What is the chance that a essay question about the biological importance of water will come up?!!
Slim I think! Well I hope it don't come up because I would be screwed haha!

So helicase for semi-conservative replication & transcription !?

Yep, it anneals the 'sticky ends' of the plasmid and the gene

Right so FSH stimulates Oestrogen production from the follice which is maturing, but then oestrogen inhibits FSH, but at it's peak oestrogen stimulates FSH which again stimulates more oestrogen ( Is this the positive feedback part to focus on) ?
The bit I highlighted you don't need to worry about though.

The positive feedback you need to worry about:

An increase in Oestrogen production (from the follicles) allows for a critical point to me reached. At this critical point, Oestrogen stimulates the production of FSH and LH. (hence causing ovulation).

The sticky end pair up and the ligase is used to join phosphate sugar framework of the 2 sections of DNA

Any idea why it stimulates FSH and not just LH on its own as this is the main to cause ovulation or is it because they are both from the pituitary gland ?

Basically write brief intro, then 3/4 main paragraphs and then a brief conclusion . Don't waste to much time on intro/conclusion :-)
