The interplay between ribonucleic acid (RNA) and proteins is not only important for maintaining cellular homeostasis but is also at the center of the tug-of-war between virus and host. Until now, there has been no method ...

A group of Skoltech researchers under Dr. Olga Sergeeva's supervision studied the functions of a long non-coding RNA, which is "read" from the genome, but does not carry the information about protein structure. In experiments ...

The functioning of certain regions of a few genes in cetaceans (whales, porpoises and dolphins) may explain why the Blue whale (Balaenoptera musculus) can reach lengths of up to 30 meters—almost 10 m more than a bus—while ...
