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 ...

Metacaspases, ancestral homologues of the caspase family, are pivotal cysteine proteases found in a wide range of unicellular organisms, including yeasts, algae, and phytoplankton. These enzymes ...

The study of these microorganisms will make it possible to better understand the processes of changes in DNA and RNA MOSCOW, August 4. /TASS/. Scientists from Tyumen State University and Papanin ...

How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food ...

Learn how one-celled organisms, or single-celled organisms, helped build complex life.

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 ...
