Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...

The more researchers examine RNA, the more surprises they ... In comparison, eukaryotic cells contain two types of rRNA genes that give rise to four rRNA species: the 28S, 5.8S, 5S, and 18S ...

The main types of rRNA include: Small Subunit rRNA ... This discovery led to the concept of the ribosome as a ribozyme, an RNA molecule with enzymatic properties. The catalytic center of the ribosome, ...

RNA cleavage can occur either: (i) by a transesterification mechanism that yields 2’,3’-cyclic-PO 4 and 5’-OH ends; or (ii) via a hydrolytic mechanism that leaves 3’-OH and 5’-PO 4 ends. RNA repair ...
