DNA Molecules That Shorten and Thicken During Cell Division Are

Question

​DNA molecules that shorten and thicken during cell division are known as _____.
A) ​chromatids
B) ​chromatin units
C) ​chromosomes
D) ​ribosomes

Accepted Answer

Chromosomes are the structures formed by coiled and condensed DNA that become visible during cell division. They consist of two identical sister chromatids held together by a centromere. Chromosomes shorten and thicken during cell division to facilitate their separation into daughter cells. Chromatin refers to the uncoiled and dispersed form of DNA during interphase, while ribosomes are responsible for protein synthesis and not involved in chromosome structure.
