Answer: The correct answer is-
B-The strands are different.
Mutation can be described as the permanent change in the genetic material of an organism ( DNA, deoxyribonucleic acid).
Replication of DNA is a process by which a double stranded DNA molecule produces two molecules of DNA, which are identical to each other.
During this process, two DNA strands are first separated and act like a template strand. Using DNA template strand, enzyme DNA polymerase adds dNTPs ( deoxyribonucleoside triphosphate) and syntheisizes new strands of DNA.
If mutation occurs during replication, there will be a change in the nucleotide sequence of the newly synthesized strand, making the strands different.
Thus, option B) is the right answer.
