Which of the following best describes the relationship between a chromosome and a chromatid?

A chromosome is a part of a chromatid, making up only a small section of its genetic material.

A chromatid is a larger structure that contains multiple chromosomes within it.

A chromosome is a single, replicated DNA molecule, while a chromatid is one of the two identical copies of that molecule joined at the centromere.

A chromosome and a chromatid are essentially the same thing, just different names used at different stages of cell division.
