what are the three main types of rna and what do they do
As far as I can remember, the 3 types are mRNA, tRNA, and rRNA. mRNA is the short term for Messenger RNA. mRNA carries information for the ribosomes in cells. tRNA is short â¦ for transfer RNA. They transfer a specific amino acid to a growing polypeptide chain to the ribosomes during translation.) Transport RNA (tRNA). - transports each amino acid to the ribosomes as it is specified by the coded messengers in mRNA. 3) Ribosomal RNA (rRNA). -the RNA present in the ribosomes including several dozens of protein.
Rating Newest Oldest. Best Answer: My research tells me there are 4 types of RNA... tRNA is the information adapter molecule. It is the direct interface between amino-acid sequence of a protein and the information in DNA Messenger or mRNA is a copy of the information carried by a gene on the DNA.The role of mRNA is to move the information contained in DNA to the translation machinery.Ribosomal RNA (rRNA) is a component of the ribosomes, the protein synthetic factories in the cell Small nuclear RNA (snRNA) is the name used to refer to a number of small RNA molecules found in the nucleus.he role of mRNA is to move the information contained in DNA to the translation machinery.
