June 16, 2004: I have a bunch of questions about genes, their locations on chromosomes, and "junk" DNA. Do genes on one chromosome have some functional characteristic or are genes scattered across chromosomes without regard to their function? How important is the position of a gene within the DNA? Have any experiments been done to show whether "junk" DNA is important?
