Answer

The three types of RNA are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). Messenger RNA is transcribed from DNA in the nucleus and carries the code to make proteins. Transfer RNA transports amino acids to the ribosomes to add to the growing polypeptide chain. Ribosomal RNA makes up a portion of ribosomes.
