why is dna copying essential for life?

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. 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. But the subtle variations produced during reproduction can survive and is the basis for evolution.
