Question

15. “DNA copies generated during reproduction will be similar but may not be identical to the
original." Justify this statement.​

Answer 1

Answer:

this statement is true as copying of DNA also accompanies the creation of an additional cellular apparatus.

Answer 2

DNA copies generated will be similar, but may not be identical to the original as some variations  are so drastic that new DNA copy cannot work with the cellular apparatus it inherits. Such a newborn cell  will simply die. Therefore, there could be many other variations in the DNA copies that would not lead to  such a drastic outcome. Thus, the surviving cells are similar but slightly different from each other. This  tendency of variation during reproduction is the basis for evolution .
