Number the following steps in the correct order and tell which stage it occurs in:
a cleavage furrow or cell plate forms, separating the nuclei.
chromosomes line up at the equator and chromatids are attached to spindle fibers.
nuclear membrane and nucleolus reappear.
genetic material replicates and is joined at the centromere.
centromeres divide and single-stranded chromosomes move to the poles.

The correct answer is given below:

Explanation:

1. A cleavage furrow or cell plate forms, separating the nuclei - Cytokinesis.  During cell division, after division of nucleus, cytoplasm divides by furrow in an animal cells and by cell plate formation in the plant cells.

2. Chromosomes line up at the equator and chromatids are attached to spindle fibres—Metaphase. During metaphase all the chromosomes get arranged on the equatorial plane or the central plane

3. Nuclear membrane and nucleolus reappear- Telophase. The nuclear membrane starts to form around each of the daughter chromosomes and nucleolus also reappears in the daughter nuclei.

4. Genetic material replicates and is joined at the centromere- S-phase of the interphase. Duplication or copying of the DNA occurs in this phase  

5. Centromeres divide and single-stranded chromosomes move to the poles- Anaphase.  During anaphase, the sister chromatids of each chromosome gets separated and move to the opposite poles.
