Question

Why is it necessary for the DNA to replicate prior to cell division?

a. so that each daughter cell will have 23 chromosomes
b. so that each daughter cell will have a complete copy of the genetic material
c. so that each daughter cell will have 46 homologous chromosomes
d. so that each daughter cell will have 2 sister chromatids

Answer 1

the answer is b. because you wouldn't want a daughter cell that didn't have all necessary to be a complete cell, and this could be messed up if the DNA didn't replicate prior to cell division

Answer 2

B

Step-by-step explanation:

replication is just to attempt to ensure that the daughter cells have the full set of DNA (genome) as their parents did as well
