Ribonucleic acid (RNA) is a ubiquitous family of large biological molecules that perform
multiple vital roles in the coding, decoding, regulation, and expression of genes.
Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute
the three major macromolecules essential for all known forms of life. Like DNA, RNA is
assembled as a chain of nucleotides, but is usually single-stranded. Cellular organisms use
messenger RNA (mRNA) to convey genetic information (often notated using the letters G, A, !
and C for the nucleotides guanine, adenine, uracil and cytosine) that directs synthesis of
specific proteins, while many viruses encode their genetic information using an RNA genome.
Some RNA molecules play an active role within cells by catalyzing biological reactions,
controlling gene expression, or sensing and communicating responses to cellular signals. One
of these active processes is protein synthesis, a universal function whereby mRNA molecules
direct the assembly of proteins on ribosomes.
This process uses transfer RNA (tRNA) molecules to deliver amino acids to the ribosome, where
ribosomal RNA (rRNA) links amino acids together to form proteins.
