It appears that the “double helix” of DNA is not the only source for heredity. DNA contains millions of proteins and other molecules that determine which genes can produce transcripts and which cannot. New cells can inherit those molecules. This means that there is a second channel through which heredity can flow. (Zimmer, Carl. NYT Science. November 2008. Article.)
