Why is it necessary for DNA to replicate?


A. DNA has to replicate to give more location from which proteins can be created.

B. DNA can break down randomly so more copies ensure that all pieces are present in the nucleus.

C. DNA must be copied before a cell can divide.​

Answer: A. DNA has to replicate to give more location from which proteins can be created.

Explanation:

DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

The process of DNA duplication is called DNA replication. Replication follows several steps that involve multiple proteins called replication enzymes and RNA. In eukaryotic cells, such as animal cells and plant cells, DNA replication occurs in the S phase of interphase during the cell cycle.

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
