Question
While joined, _____ make up one chromosome.
Group of answer choices:
- sister chromatids
- chromatin
Solution
The correct choice to fill in the blank is sister chromatids.
Explanation:
During the cell division process, specifically in the phases leading up to mitosis (specifically during the S phase of interphase), a chromosome replicates its DNA, resulting in two identical copies known as sister chromatids. These chromatids remain joined together at a region called the centromere until they are separated during cell division. Thus, while joined, sister chromatids indeed make up one chromosome.
In summary, the complete statement would read: "While joined, sister chromatids make up one chromosome."
