(S4)C8 - DNA, genes and protein synthesis

Question 1

Describe the role of a ribosome in the production of a polypeptide. Do not include transcription

Answer 1

• ribosome binds to the start codon of mRNA (AUG)
• 2 tRNA carries 2 anticodons to bind and associate with complementary codon on the binding site of mRNA
• Ribosome catalyses the formation of peptide bond between amino acids
• move along (mRNA to the next codon)
