A ubiquitous but little-known marine organism, the choanoflagellate, is the last one-celled ancestor of humans and provides insight into how cells learned to assemble into multicelled organisms. The ...

Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in ...

The transition to multicellularity enabled the evolution of large, complex organisms, but early steps in this transition remain poorly understood. Here we show that multicellular complexity, including ...

Molecular cloning is usually carried out on one gene or small DNA segment at a time. However, cloning technology has advanced to the stage that scientists have begun cloning genomes of entire ...

Berkeley -- The newly sequenced genome of a one-celled, planktonic marine organism, reported today (Thursday, Feb. 14) in the journal Nature, is already telling scientists about the evolutionary ...
