Question

"Prediction of the sequence of amino acids from the nucleotide sequence in mRNA is very easy, but the exact prediction of the nucleotide sequence in mRNA from the sequence of amino acids coded by mRNA is difficult". Which properties of the genetic code is the reason for the above condition? Explain.

Answer 1

The genetic code is degenerate. There are more than one codon which can code for the same amino acids. So it is difficult to trace the nucleotide sequence which is present on the mRNA with the help of the amino acid sequence.
