A change in a sequence of DNA occurs so that the mRNA codon reads AUC rather than AUU. Both of these code for the amino acid isoleucine. Argue that this is not a mutation.

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

A DNA sequence needed for coding a peptide is given below. CAAGTAAATTGAGGACTC" (Hint: Codons and Aminoacids) CAAGTAAATTGAGGACTC" UUA - Leu CCU - Pro CAU - His ACU - Thr GUU - Val GAG - Glu Write the complementary mRNA coding sequence for this.
