Protein Synthesis

• Protein synthesis

  1. DNA unzips

  2. Complementary bases pair up on mRNA

  3. mRNA leaves nucleus and enters cytoplasm

  4. Ribosome attaches to mRNA and reads code to assemble amino acids

  5. Protein is synthesised in cytoplasm
• Protein


  Organic compound made up of amino acid molecules, needed by the body for cell growth and repair
• Proteins

  • Can be functional (e.g. enzymes, antibodies, haemoglobin, hormones)
  • Can be structural (e.g. collagen)
• The mRNA molecule is complementary to the DNA sequence, with A pairing with U.
