Describe the function of the 3 main types of rna.

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.

Hope I helped!
