Question

Newly formed DNA copies may not beidentical at times give 1 teason

Answer 1

During the process of replication of DNA most of the base sequence in the new copies are identical to those in the parent DNA. However some changes can occur either due to mutation or due to minor errors during replication process. Thus, newly formed DNA copies may not be identical at times

Answer 2

This is because of DNA inaccuracies. No biochemical reaction is reliable. While DNA replication there is some variation. So they may not be identical for all the times.

Hope dis will hlp uh!!!!!
