what is an RNA

Expert Solution

Ribonucleic acid is the full form of RNA. It is a polymeric molecule essential in various biological roles such as regulation and expression of genes and also in coding n decoding.. RNA is assembled as a chain of nucleotides. It is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand. Cellular organisms use messenger RNA (mRNA) to convey genetic information using the nitrogenous bases of guanine, uracil, adenine, and cytosine, denoted by the letters G, U, A, and C, that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.

There are many types of RNA. The three most well-known are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), which are present in all organisms. RNAs primarily carry out biochemical reactions, similar to enzymes. Some have complex regulatory functions in cells., RNAs play important roles in both normal cellular processes and diseases.
