RNA

Messenger RNA, or mRNA, are molecules that carry genetic information from the DNA in every cell in the body to create specific proteins.

Using single-cell RNA sequencing, which identifies gene activity in individual cells, the researchers observed that microplastics altered several cell types involved in atherosclerosis.

Researchers from Stockholm University have -- for the first time ever -- managed to successfully isolate and sequence RNA molecules from Ice Age woolly mammoths.

Proteins, of course; RNA acts as the major-domo, a bridge between the castes.

Their research centers on TERRA, an RNA molecule that helps maintain the ends of chromosomes -- the regions of DNA that support cell stability and overall health.
