1.	Codon degeneracy means that(a) several amino acids are coded by more than one codon(b) one codon can code for many amino acids(c) one amino acid can be coded by only one codon(d) the codons are triplet nucleotide sequences
Answer» Answer is : (a) several amino acids are coded by more than one codon There are 64 codons present in each living organism, out of which, 61 codons represent or code for amino acids and rest three are stop codons. Thus, there are more codon combinations than there are amino acids. The genetic code is described as degenerate because more than one codon sequence can code for the same amino acid.

Answer»

Answer is : (a) several amino acids are coded by more than one codon

There are 64 codons present in each living organism, out of which, 61 codons represent or code for amino acids and rest three are stop codons. Thus, there are more codon combinations than there are amino acids. The genetic code is described as degenerate because more than one codon sequence can code for the same amino acid.
