Cell Cycle – Online MCQs Test – Biology 9th

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

2. What occurs in metaphase of mitosis?

3. The homologous chromosomes exchange their parts of chromatid at:

4. Location of centromere at the end of chromosomes.

5. In this sub-phase, the spindle fibres are formed; nuclear membrane and the nucleolus disappear.

6. Cell death caused by external factors is called:

7. A chromosome has:

8. During pachytene sub-phase, the separation of paired chromosomes is incomplete and they are in contact with each other at one or more points called:

9. Stage of mitosis in which chromatids reach the poles and their movement ceases.

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

11. A type of cell division in which spore mother cell produce spores

12. A cell cycle has:

13. Cell division in which single cell divides into four daughter cells and number of chromosomes becomes half in each daughter cell is called:

14. Sequence of physiological changes by which cell commit suicide.

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

16. The interphase is divided further into:

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

18. The pairing of homologous chromosomes is known as:

19. Each bivalent is composed of four chromatids and is known as:

20. Meiosis I consists of:
