BigField GEG Tech's insight:
RNA is a fundamental molecule that codes for protein and controls gene expression, playing a part in regulating many cell responses and vital processes. The genetic information contained in premature messenger RNA (mRNA), before being converted to proteins, needs to be processed and cleared of its non-coding sections, known as introns. In several simpler organisms, this key process is carried out by group II introns, enzymes entirely made up of RNA (different from the true protein enzymes) called ribozymes that are able to self-cleave by removing themselves from the mRNA filament and thereby promoting RNA maturation.

BigField GEG Tech's insight:
A set of biochemical processes crucial to cellular life on Earth could have originated in chemical reactions taking place on the early Earth four billion years ago, believes a group of scientists from the Francis Crick Institute and the University of Cambridge.
