Messenger RNA acts to carry genetic sequence information between DNA and ribosomes, directing protein synthesis.Ribosomal RNA is a major component of the ribosome, and catalyzes peptide bond formation.he three universal types of RNA include transfer RNA (tRNA), messenger RNA (mRNA), and ribosomal RNA (rRNA).
