How many copies of the gene - (Apr/02/2010 )


I have a doubt! Is there a way to know how many copies of a specific gene I have in the genome?
I'd like to know the number of copies of my gene of interest in the genome.



Assuming you mean paralogs (i.e. gene duplication events in the same organism, thus the having the same or very closely related DNA), you could do a Southern blot to find out how many copies there are. If the genome is sequenced, you could just BLAST the sequence of the gene against the genome sequence.
