2)

DNA replication is the basis for biological inheritance. It is a fundamental process occurring in all living organisms to copy their DNA. The consistency of DNA copying during reproduction is important for the maintenance of body design features that allow the organism to use a particular niche. 

 

There may be variations in the the DNA copying reactions occuring during reproduction. As a result, the DNA copies generated will be similar, but may not be identical to the original. Some of these variations might be so drastic that the new DNA copy cannot work with the cellular apparatus it inherits. Such a newborn cell will simply die. On the other hand, there could still be many other variations in the DNA copies that would not lead to such a drastic outcome. Thus, the surviving cells are similar to, but subtly different from each other. This inbuilt tendency for variation during reproduction is the basis for evolution. The consistency of DNA copying during reproduction is important for the maintenance of body design features that allow the organism to use that particular niche. Reproduction is therefore linked to the stability of populations of species.
