WHY does DNA coil up to form chromosomes?

Question

A. The cell can't grow if the DNA is not coiled up into chromosomes

B. DNA needs to be coiled up into chromosomes in order for the genes to work

C. It's easier to move the DNA around and into new cells when it's packaged up into chromosomes

Answer 1

The best answer is:

C. It's easier to move the DNA around and into new cells when it's packaged up into chromosomes.

DNA coils up to form chromosomes primarily to facilitate the orderly segregation of genetic material during cell division. This packaging helps ensure that each daughter cell receives the correct amount of DNA. While there are aspects of cell growth and gene expression that are influenced by DNA organization, the primary reason for coiling into chromosomes is related to the efficient movement and distribution of DNA during cell division.
