The tiny microorganisms pack their genes closely together, and don't carry around a lot of extraneous DNA, so-called junk DNA that fills in the gaps between genes. Some 90 percent of the complete genome sequence of the bacteria E. coli contains sequences of DNA that code for protein, while 90 percent of the human genome is non-coding junk DNA.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/293512981" height="1" width="1" /></p> http://science-nature.marc8.com/ancient-protein-balances-gene-activity-and-silences-foreign-d#comments Top stories complete genome sequence gene activity junk dna silences tiny microorganisms http://science-nature.marc8.com/crss/node/4723 Mon, 19 May 2008 10:15:15 -0500 admin 4723 at http://science-nature.marc8.com
