Why must DNA be packed into chromosomes before mitosis or meiosis can occur?
A)In their unpacked state, the strands of DNA would be difficult to pull apart during cell division.
B)The zygote would be unable to live if the DNA were not packed into chromosomes.
C)We would be unable to see the karyotype if the DNA were not packed into chromosomes.
D)Some of the genes would escape during cell division if they were not packed tightly into chromosomes.

During cell division, the DNA needs to be separated and distributed evenly to the daughter cells. If the DNA strands were in their unpacked state, they would become tangled and difficult to separate, leading to errors in distribution and potentially harmful mutations. Therefore, packing the DNA into chromosomes ensures that the DNA can be separated and distributed evenly during cell division.
