Whose experiments cracked the DNA and discovered unequivocally that a genetic code is a ‘triplet’

(b) Morgan and Sturtevant
(c) Beadle and Tantum
(d) Nirenberg and Mathaei

Correct Answer:

Nirenberg and Mathaei

Explanation:

Nirenberg and Mathaei (1961) experi-men-tally proved that a single amino acid is determined by a sequence of three nitrogen bases. The sequence of three nitrogen bases determining a single amino acid is called a triplet code. Nirenberg and Mathaei experiments cracked the DNA and discovered unequivocally that a genetic code is a triplet.
