By the time a normal cell divides, you can assume that
a. the cell's surface area has become larger than its volume
b. the cell's volume has become larger than its surface area
c. the cell has replicated all its dna
d. the cell's mitochondria have been destroyed

c. the cell has replicated all its DNA

Explanation:

It is important to remember that the genome which is the DNA sequence is a vital part of the cell. The genome completion or DNA sequence completion is an important stage before the cell division begins as the chromosome replicates before division. This chromosome replication results in two separate but identical chromosomes. These identical chromosomes are passed on to the new cells formed through cell division. Hence, it is assumed that the ell has replicated all its DNA before division.

the correct answer is d
