<span>Three types of RNA are:
MRNA:
mRNA is transcribed from a DNA template, and carries coding information
to the sites of protein synthesis: the ribosomes. Here, the nucleic acid
polymer is translated into a polymer of amino acids: a protein.
TRNA: transfers a specific amino acid to a growing polypeptide chain at
the ribosomal site of protein synthesis during translation. Basically
forms the protein.
RNA: provide a mechanism for decoding mRNA into amino acids and to
interact with the TRNA's during translation by providing peptidyl
transferase activity. Basically acts as a coordinator for the actions of MRNA and TRNA. </span>
