Cell Cycle – Online MCQs Test – Biology 9th

1. A chromosome has:

2. In mitosis, the phase of nuclear division is:

3. Stage of meiosis in which centromeres shorten and the paired chromatids are pulled away from one another.

4. In this phase of meiosis, chromosomes become uncoil, nucleolus reappears and two daughter nuclei formed.

5. Meiotic error, where a pair of homologous chromosomes fails to separate from one another called:

6. In animals, meiosis takes place in germ cell to produce:

7. Chromatin fiber is made of:

8. During this sub-stage of prophase I, chiasmata moves from the centromere towards the ends of the chromosomes like a zipper.

9. The exchange of segments of chromatids at chiasmata between the homologous chromosomes is called:

10. A cell cycle has:

11. In mitosis, cytoplasm divides and two daughter cells are formed during:

12. Programmed changed which lead to sequence of physical changes in cell by which cells commit suicide collectively called:

13. Although mitosis is a continuous process, but for the study point of view it is divide into:

14. During the first sub stage of prophase I, the chromatin network break into specific number of long thin beaded thread called:

15. It consists of the longest phase of meiosis:

16. The production of somatic cells, such as blood cells, depends on:

17. During this phase, replication of DNA occues.

18. In mitosis, the phase of cytoplasmic division is called:

19. It is the period of non-division.

20. In plant cells, cytokinesis occurs by developing:
