Whose experiments cracked the genetic code and discovered unequivocally that genetic code is triplet
Whose experiments cracked the genetic code and discovered unequivocally that genetic code is triplet
The correct option is B Nirenberg and Mathaei
The Nirenberg and Matthaei experiment was a
scientific experiment performed in May 1961 by Marshall W. Nirenberg and his
post-doctoral fellow, J. Heinrich Matthaei at the National Institutes of Health
(NIH). The experiment deciphered the first of the 64 triplet codons in the
genetic code by using nucleic acid homopolymers to translate specific amino
acids.In the experiment, an extract from bacterial cells that could make
protein even when no intact living cells were present was prepared. Adding to
this extract an artificial form of RNA consisting entirely of uracil-containing
nucleotides (polyuridylic acid or poly-U), caused it to make a protein composed
entirely of the amino acid phenylalanine. This experiment cracked the first
codon of the genetic code and showed that RNA controlled the production of
specific types of protein.
So,the correct option is 'A'.
