The three universal types of RNA include transfer RNA (tRNA), messenger RNA (mRNA), and ribosomal RNA (rRNA). 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). Messenger RNA acts to carry genetic sequence information between DNA and ribosomes, directing protein synthesis.
There are three main types of RNA: 1  Messenger RNA (mRNA) transcribes genetic information from the DNA found in a cell's nucleus, and then carries this information to the cell's cytoplasm and ribosome. 2  Transfer RNA (tRNA) is found in a cell's cytoplasm and is closely related to mRNA as its helper.
