    I got a U :woo:
    Just resit, you need 65 for a B, so there really isn't any point. You're extremely intelligent, I just think the questions were a bit wtf? They can't make the same mistake in June, so yeah.
    yea.. and same for you too...

    Module 2 Version 3: http://www.mediafire.com/?1zz3n5r5kdt
    Pleaseeeeeeeeeee help me!!!!

    Is this correct:
    1) Two chromatids (sister chromatids joined at the centromere) form a chromosome?

    2) Okay, this bit confuses me. Is chromatin DNA that is "uncondensed"? So, am I right in thinking that it is not wrapped around histones? And when chromatin does condense, it does wrap around histones?

    I'm so baffed.

    :lol:

    1) correct

    2) i think so although i'm not 100% sure. Doesn't it wrap around histone:hmmmm2:?

    I don't have any really Basically I wrote up all my notes into a big notebook, did the quick check questions from the revision guide, revised things as I went along that I wasn't as confident with, did the sample exam questions in the revision guide/textbook, revised again anything I lost marks on I didn't do anything special really.

    1) is correct....1 chromatid can also be called a chromosome, depending on their stage of development
    2)Methylation of histones. The allele is wrapped around the histones, and when their tails are methylated, the histones stay closely condense and do not let any transcription factors bind to their elements for transcription-therefore the histones are wrapped around at all times, but is the substance that condenses and uncondenses ----number two is partially correct

    Can you break that down to me? Imagine I'm a 8 year old and I ask you what chromatin is/what the difference between chromosomes and chromatin is?

    A chromosome is a discrete portion of chromatin. You could imagine a closet full of cotton shirts, each a different color. Each shirt could represent a chromosome. The material they are all made of is still cotton, which could represent chromatin. If you cut all the shirts up with scissors, you'll still have cotton; i.e. there is still some recognizable structure. Similarly, you could enzymatically cut up chromosomes and still have recognizable chromatin structure.

    so what im saying is that chromosomes are built up by a mixture of DNA and proteins (histones and other elements)...it is this that decondenses such as in interpahse and condenses


    CHROMATIN: A complex of DNA and proteins (histones and nonhistones) that forms each chromosome and is found in the nucleus of all eukaryotes. Decondensed and threadlike during interphase.

    CHROMATIN CONDENSATION: Compaction of different regions of interphase chromosomes that is mediated by the histones.

    A few of the things are explained in this video.
