Translation 2.1.3 g

Question 1

Describe the process of translation

Answer 1

1) mRNA binds to a ribosome
2) tRNA carries an amino acid to the ribosome, which is complimentary to the codon
3) A second tRNA brings another amino acid
4) The two amino acids bind, by a peptide bond, and the process repeats
5) A polypeptide chain forms
6) Process continues until a stop codon is reached

Question 2

Name the organelle involved in translation

Answer 2

Ribosome

Question 3

a) Anticodon on tRNA
b) The template base sequence

Answer 3

a) UAG
b) TAG

Question 4

A strand of mRNA has 64 codons yet only 63 amino acids were produced. Suggest why

Answer 4

Stop codon
