All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required for that organism. However, DNA does more than specify ...

Importantly, these multicellular organisms have a finite life span, naturally degrading after four to six weeks. This “kill ...

Later, animals—multicellular organisms—evolved, developing from a single egg cell to form complex beings. This embryonic development follows precise stages that are remarkably similar between ...
