    Can anyone explain to me this stage in genome sequencing as I really do not understand (it is the first stage) :

    From top of pg 167 in OCR textbook:

    'Genomes are first mapped to identify which part of the genome (I.e. Which part of the chromosome/ section of chromosome) they have come from. Information that is already known is used e.g. Using the location of micro satellites'

    I understand everything else in the method apart from this. I thought a genome was the entirety of an organisms genetic information so how can its location on a genome be identified? Also, what is the purpose of the microsatelites?

    Is this a mistake or am I just being really thick? Please help

    Sorry you've not had any responses about this.

    Why not try posting in a specific subject forum- you might have more luck there.

    It looks like a mistake. Like you said, the genome is an organism's entire genetic information. It should say genes.

    Look at figure 1 on page 166 and the text underneath, I think they meant that the 'BAC' location is identified on the genome. If that makes sense
