  • RNA differs from DNA in several ways.
  • There are three main types of RNA: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA) Each type plays a different in role in making proteins.
  • More on the roles of the RNAs will be discussed in additional concepts.
  • The three types of RNAs are: mRNA, rRNA, and tRNA.
  • mRNA copies the genetic instructions from the nucleus to the cytoplasm.
  • Transfer RNA brings amino acids to ribosomes, where they are joined together to form proteins.
