Explanation:

1. Mitosis is the phase of the cell - cycle that divides the nucleus.
2. The cell cycle is an ordered series of events for cell growth and division to produce two new daughter cells.
3. Cytokinesis is the division of organelles and cytoplasmic materials.
4. Kinetochore is a protein associated with the centromere of each sister chromatid for mitotic spindle attachment.
5. During prophase, the nucleolus disappears and centrosomes move to opposite poles.
6. The centromere is the region of a chromosome where spindle microtubules attach during cell division.
7. Chromosomes line up on the equatorial plate during metaphase.
8. Sister chromosomes are separated during anaphase and pulled to opposite poles.
9. Nuclear membranes form around chromosomes at the end of telophase.
10. The centrosome is an organelle near the nucleus with centrioles (in animal cells) from which spindle - fibers develop.
11. Chromatin is a complex made up of DNA and protein.
12. Replication is the duplication of each chromosome during the S - phase of interphase resulting in sister chromatids.
13. Interphase is one of the two stages in the cell cycle where the cell grows and chromosomes are duplicated.
14. The mitotic spindle is a structure composed of microtubules that separates sister chromatids into daughter cells during mitosis.
15. S phase is the synthesis phase of interphase where DNA replication occurs.
16. Sister chromatids are two identical copies of each chromosome attached at the centromere region.
