Which of the following describes a chromatid? A) A fiber of condensed chromatin B) A duplicated chromosome attached to centromeres C) The visible form of DNA during interphase D) A structure made of histones alone

Understand the Problem

The question is asking for a correct definition or description of a chromatid from the given options. It requires the user to have a knowledge of genetics and cell biology.

Answer

A duplicated chromosome attached to centromeres.

A chromatid is one of the two identical halves of a duplicated chromosome, which are attached to each other by a common centromere prior to cell division.

Answer for screen readers

A chromatid is one of the two identical halves of a duplicated chromosome, which are attached to each other by a common centromere prior to cell division.

More Information

Chromatids exist after DNA replication, making up the duplicated chromosome. Each chromatid is eventually separated into its own cell during cell division to ensure both new cells have a complete set of chromosomes.

Tips

Mistakes may arise by confusing chromatin (which is a complex of DNA and proteins) with chromatids, which refer to the replicated chromosomes themselves.
