Protein Synthesis 14.1-14.2

Transcription- Turn DNA into mRNA

Translation- Turn mRNA into Protien

DNA’s Role-

Depends on which type!

  1. mRNA *messenger RNA*

  • Carries copies of DNA instructions for making proteins from the nucleus to ribosomes in the cytoplans


  1. rRNA *ribosomal RNA*

  • Makes up major part of ribosomes

  • Site of protein production

  • Works by reading (TRANSLATING) the mRNA code into a protein

  • Brings together mRNA and tRNA, linking amino acids together with a peptide bond


  1. tRNA *transport RNA*

  • Consists of two parts- amino acids and anticodon (3 unpaired bases)

  • transfer / carrier amino acids from the cytoplasm to the ribosome and matches them to coded mRNA messages.
