MicroRNAs (miRNAs) — a class of small RNAs with a role in the regulation of gene expression — had until now been found only in multicellular organisms. Now, Wang, Qi and colleagues provide the first ...
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 ...
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 ...
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 ...
