Re:Introns ?= junk DNA (Score 2)

Actually, introns != junk DNA . Introns are intervening sequences within genes that are spliced out before the RNA is translated into protein. Introns often contain regions important for regulation of gene expression and serve as a way to generate more diversity in gene products (by the production of alternatively spliced RNA transcripts). Junk DNA refers to regions of DNA between genes with function (if any) unknown. Just want to keep the discussions accurate.
