Gene regulation differences between humans, chimpanzees very complex

Changes in gene regulation have been used to study the evolutionary chasm that exists between humans and chimpanzees despite their largely identical DNA. However, scientists have discovered that mRNA expression levels, long considered a barometer for differences in gene regulation, often do not reflect differences in protein expression -- and, therefore, biological function -- between humans and chimpanzees.http://feeds.sciencedaily.com/~r/sciencedaily/~3/u...
