Question

A segment of DNA, 'TTG AGG GGG ATG' was translated into an oligopeptide with the amino acids, Lysine – Serine – Proline – Tyrosine. (a) Write the codons in correct sequence for the four amino acids. (b) If first adenine in DNA is substituted by guanine, what will be the sequence of amino acids in the new oligopeptide? (c) Write the anticodons for these amino acids.

Assertion (A) : One of the property of genetic code is degeneracy. Reason (R) : Some amino acids can be coded by more than one codon.
