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 ...
Thus, RNA molecules play numerous roles in both normal ... Although these molecules are only 21 to 25 base pairs in length, they also work to inhibit gene expression. Specifically, one strand ...

RNA is formed by linking molecules of ribose (a monosaccharide) with phosphate groups that bind to four types of nitrogenous bases: adenine (A), guanine (G), cytosine (C) and uracil (U). Both the ...
RNA viruses pose significant challenges to public health due to their high mutation rates and diverse mechanisms of infection which allow them to rapidly adapt to new hosts and evade therapeutic ...
