Why is the process of DNA replication necessary?

A. It is during the process of replication that the repair of any damaged regions of the DNA sequence occurs.
B. DNA replication results in the production of mRNA that can then be used to produce protein molecules.
C. For any protein being produced, multiple copies of the encoding gene must be present in the cell; therefore, multiple copies of the DNA helix are required.
D. Each cell that results from cell division will then have a complete set of genetic information.



Answer :

Final answer:

DNA replication is essential for cell division to maintain genetic integrity by ensuring accurate copying of DNA.


Explanation:

DNA replication is necessary for cell division to ensure each daughter cell receives an identical copy of the genetic information encoded in the DNA. The process involves a variety of enzymes that unwind the DNA, separate the strands, and synthesize new complementary strands based on the original templates. Errors in replication can lead to dysfunctional genes, emphasizing the importance of precise DNA copying mechanisms.
