translation

Question 1

outline the initiation process of translation

Answer 1

1) mRNA binds to small subunit of ribosome
2) tRNA molecule with complementary anticodon (carrying its amino acid) to exposed codon form H bonds together
3) another tRNA molecule with complementary anticodon to next codon base pairs
4) peptidyl transferase forms peptide bonds between the two aa
5) tRNA leaves the ribosome leaving behind its aa

Question 2

outline the process of elongations

Answer 2

1) ribosome moves along mRNA exposing more codons
2) more complementary tRNA bring aa and the polypeptide chain grown

Question 3

outline the process of termination

Answer 3

1) when the ribosome reaches a stop codon on the mRNA the ribosome and mRNA detach
2) the polypeptide chain can now take up its tertiary structure
