Whose experiments cracked the DNA and discovered unequivocally that a genetic code is a 'triplet'
Hershey and Chase
Morgan and Sturtevant
Beadle and Tantum
Nirenberg and Mathaei
As learnt
Chemical method developed by Har Gobind Khorana -
This was instrumental in synthesising RNA molecules with difined combination of bases.
- wherein
Marshall Nirenberg's cell free system for protein synthesis finallt helped the code to be deciphered.
Nirenberg and Mathaei (1961) experimentally proved that three nitrogen bases codes for single amino acid, called as triplet codon.
