Translation

Question 1

What is is

Answer 1

The production of polypeptides from sequence of codons carried by the mRNA

Question 2

Describe the process

Answer 2

1. mRNA moves from the nucleus through a nuclear pore to the cytoplasm and the start codon attaches to ribosome
2. tRNA with a complementary anticodon moves to the ribosome and pairs with the first mRNA codon
3. The ribosome moves along the mRNA to the next codon and again pairs with a complimentary tRNA to bring the 2 amino acid-carrying tRNA’s together
4. Energy released from ATP is used to form a peptide bond between the amino acids
5. The ribosomes moves to the 3rd mRNA codon, releasing the first tRNA and pairing up with a 3rd
6. When the ribosomes reaches a stop codon, the polypeptide is complete and the mRNA and tRNA’s are released from the ribosome
7. The tRNA molecules released from the ribosome can then be reused
