A that gene provides both protection and destruction

The family of ENDOU enzymes is found in most organisms, yet its functions are only poorly understood. In humans, it has been connected with cancer. RNA viruses, such as SARS-CoV2, contain a gene corresponding to ENDOU, and ...

Video: Green algae reveals that one mRNA encodes many proteins

Gene expression in eukaryotes was long held to be monocistronic—that is, a single gene makes messenger RNA, which encodes a single protein. Recently reported in the Proceedings of the National Academy of Sciences, a team ...
