Biology Question on the molecular basis of inheritance
Change in sequence of nucleotide in DNA is called as -
A
Mutagen
B
Mutation
C
Recombination
D
Translation
Answer
Mutation
Explanation
Solution
A mutation involves a change in the sequence of nucleotides in a nucleic acid molecule. This change will express itselfin the form ofa change in the sequence of aminoacids 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.
