Answer: false
Explanation:
Error occur during replication but it is not associated with drugs and it is mostly fixed during proofreading after replication is done by deoxyribonucleic acid (DNA) polymerase.
polymerase enzymes makes mistake where by a wrong nucleotide or too many or too few nucleotides is inserted into a sequence these mistakes are mostly fixed through various DNA repair processes.
enzymes that repairs recognize this imperfections between improperly paired nucleotides and them cut out the wrong ones while putting the right ones in their place. But some replication errors make it past these mechanisms, thus becoming permanent mutation which can then be passed down from one cellular generation to another.
