Cell Cycle – Online MCQs Test – Biology 9th

1. During this sub stage of prophase I, lengthwise pairing of chromosomes takes place.

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

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

4. The sequence of changes which occurs between one cell division and the next is called:

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

6. It is the period of cell division.

7. The mitosis phase, Karyokinesis, can be divided further for convenience into:

8. Select the mismatched:

9. It maintains chromosomes number constant from generation to generation.

10. It is the period of growth and synthesis of DNA.

11. Meiosis is a series of two divisions which result in the formation of:

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

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

14. The interphase is divided further into:

15. Rod like chromosomes with one arm very small and other very long.

16. The chromosomes are attached to half spindle fibres by their centromere and get arranged at equatorial plane during:

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

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

19. 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:

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