I am new Biopython user, I have the genomic position of a mutation, I like to retrieve its sequence with the base change (mutation), How can I do that?? Thanks ..
FYI, your question is a bit ambiguous. Do you want the entire chromosome with the change or just the flanking sequence? Also, what have you tried? People will be more likely to help you if they can see that you've put some effort into answering things yourself.
Thank you, Well I would say I want to retrieve only flanking regions.
OK, then what have you tried so far? While I (or someone else) could just post a few lines showing how to do this in biopython, there's no point in doing that if you haven't tried to figure out how to do this yet yourself.
