Zoology - Molecular Basis of Inheritance Question with Solution | TestHub

The genetic information flows from $\mathrm{DNA}\to m\mathrm{RNA}\to$ protein. A mutation involves a change in the sequence of nucleotides in a nucleic acid molecule. This change will express itself in the form of a change in the sequence of amino acids in the protein molecule synthesized through the information encoded in nucleic acid segment. Therefore mutations at molecule level can be studied both by the study of the sequence of amino acids in a protein and also by the study of sequence of nucleotides in a segment of nucleic acid.
