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 synthesized from DNA by an enzyme known as RNA polymerase during a process called transcription. ...

What is the function of ribonucleic acid?

Ribonucleic acid (RNA) is one of the two major classes of nucleic acids. The main function of RNA is cellular protein synthesis. RNA converts the instructional genetic information stored in deoxyribonucleic acid (DNA) into proteins. However, some viruses use RNA (rather than DNA) to carry the genetic information.

What is an example of ribonucleic acid?

Examples of small RNAs are transfer RNA (tRNA), 5S ribosomal RNA (rRNA), microRNA (miRNA), small interfering RNA (siRNA), small nucleolar RNA (snoRNA), Piwi-interacting RNA (piRNA), tRNA-derived small RNA (tsRNA), and small rDNA-derived RNA (srRNA).
