Notably absent is the third domain: Archaea. According to a recent report in the Journal of Clinical Microbiology, however,

That effect is caused by the different refractive indexes of the air and water, which causes the li

In the spring of 1970 two young investigators shook the foundations of molecular biology's "central dogma," which holds that DNA is transcribed to RNA, which in turn is translated into protein.
