Question

Termination of chain growth in protein synthesis is brought about by

• A. UUG, UGC, UCA
• B. UCG, GCG, ACC
• C. UAA, UAG, UGA
• D. UUG, UAG, UCG

Answer 1

The correct option is C UAA, UAG, UGA

Termination of chain growth in protein synthesis is brought about by UAA, UAG, UGA. Translation starts with a chain initiation codon or start codon and terminates with a stop codon.

The three stop codons have been given names : UAG is amber, UGA is opal, and UAA is ochre. Stop codons are also called "termination" or "nonsense" codons.
