Question

Why does a cell need to copy its DNA before it divides?
A) so both new cells have enough DNA

B) so the sister chromatids don’t have to get separated.

D) so it has a different set of instructions

Answer 1

Respuesta:

b)

Explicación:

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. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
