Which one of the following triplet codes, is correctly matched with its specificity for an amino acid in protein synthesis or as 'start' or 'stop' codon ?
Correct answer: D. UAC - tyrosine
- A. UCG - start
- B. UUU - stop
- C. UGU - leucine
- D. UAC - tyrosine
Explanation
Codon UAC is correctly matched as it codes for the amino acid tyrosine. UCG codes for serine, UUU codes for phenylalanine, and UGU codes for cysteine. The start codon is AUG, and stop codons are UAA, UAG, and UGA.
