When a cell reproduces through cell division, scientists call the reproducing cell the parent cell, and the two cells that result from the division are called daughter cells. The daughter cells are genetically identical to the parent cells. Before a parent cell starts to divide, the DNA in its nucleus replicates, or makes a complete copy of itself. Why is this process necessary?

Question

TestUstad · Accepted Answer

So that each daughter cell receives a complete set of DNA. The correct answer is B. The process of DNA replication before cell division ensures that each daughter cell receives a complete set of genetic material identical to the parent cell. Without DNA replication, the genetic material would not be distributed equally between the daughter cells, and they would not be genetically identical to the parent cell.

So that the parent cell will have an extra copy of DNA

TestUstad · Answer

So that each daughter cell will not need to synthesize proteins

TestUstad · Answer

So that each daughter cell will receive half its DNA from each parent cell
