what are the three main types of rna, and what are each of their functions?
One common homework and test question asks you to name the three types of RNA and list their functions. Here's the answer. Answer: There are actually several types of ribonucleic acid or RNA, but most RNA falls into one of three categories: 1  mRNA or Messenger RNA. 2  mRNA transcribes the genetic code from DNA into a form that can be read and used to make proteins. 3  mRNA carries genetic information from the nucleus to the cytoplasm of a cell.
Transfer RNA (tRNA) then carries the appropriate amino acids into the ribosome for inclusion in the new protein. Meanwhile, the ribosomes themselves consist largely of ribosomal RNA (rRNA) molecules.
