Some "junk" DNA may have a function
IT IS a cliché of genetics that most of the genome is junk. The genes
themselves constitute 2-3% of the DNA in a human cell's nucleus. Some
of the rest regulates the genes, but most consists of stuff that is
apparently useless or, worse, parasitic. Among the latter are the
remnants of so-called retrotransposons.
