Assertion : Genetic code is degenerate. Reason : All amino acids are coded by more than one codon.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
In genetic code there are 64 codons, in these 61 codes for amino acids called sense codons and 3 codons do not code for any amino acids, hence they function as stop codons or Non sense codons. 61 codons code for 20 amino acids, means some amino acids are coded by more than one codon, hence the genetic code is degenerate.

The scientist who gave the genetic code was a
1 Phycisist
2 Geneticist
3 Biologist
4 Biochemist
Explanation:
George Gamow, a physicist, who argued that since there are only 4 bases and if they have to code for 20 amino acids, the code should constitute a combination of bases. He suggested that in order to code for all the 20 amino acids, the code should be made up of three nucleotides.

Whose experiments cracked that a genetic code is a triplet?
1 Nirenberg and Mathaei
2 Morgan and Strulevant
3 Hershey and Chase
4 Beadle and Tatum
Explanation:
Marshall Nirenberg and Heinrich J. Matthaei cracked the DNA and discovered unequivocally that a genetic code is a "triplet". They were the first to elucidate the nature of a codon in 1961, at the National Institutes of Health. They used a cell-free system to translate a poly-uracil RNA sequence and discovered that the polypeptide that they had synthesized consisted of only the amino acid phenylalanine.They thereby deduced that the codon UUU specified the amino acid phenylalanine.
