What stage do daughter chromosomes duplicate?

Daughter chromosomes do not duplicate. They are the result of the duplication of chromosomes during S phase of interphase.

Here's a breakdown:

* Interphase: The stage of the cell cycle where the cell grows and prepares for division.

* S phase (Synthesis phase): The part of interphase where DNA replication occurs.

* Chromosomes: Structures made of DNA and proteins that carry genetic information.

* Duplication: The process of creating an exact copy of a chromosome. This creates two identical copies called sister chromatids.

* Sister chromatids: The two identical copies of a chromosome attached at the centromere.

* Daughter chromosomes: After mitosis or meiosis, the sister chromatids separate, becoming individual chromosomes. These are called daughter chromosomes.

In summary:

1. Chromosomes duplicate during S phase.

2. The duplicated chromosomes are called sister chromatids.

3. The sister chromatids separate during cell division, becoming daughter chromosomes.

Daughter chromosomes are not duplicated. They are the result of the duplication of chromosomes during S phase.
