Types of RNA

  • mRNA: Messenger RNA. Encodes amino acids sequences.
  • tRNA: Transfer RNA. Carries amino acids to ribosome during translation.
  • rRNA: Ribosomal RNA. Makes up ribosomes.
  • snRNA: Small Nuclear RNA (U1, U2, U4, U5, and U6).
  • sRNA: Small RNA. Binds to protein or mRNA targets, and regulates gene expression.
  • miRNA: Micro RNA. A family of sRNA that regulates gene expression in a sequence-specific manner.
  • siRNA:  Small Interfering RNA.
  • dsRNA: Double-Stranded RNA
  • pre-mRNA: Precursor mRNA. Contains both exons and introns.
  • mature mRNA: All introns removed.
