Cell Cycle – Online MCQs Test – Biology 9th

1. In prophase of mitosis chromatin network becomes thick and thread like structure is called:

2. It is the period of non-division.

3. It is the period of extensive metabolic activity.

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

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

6. The paired homologous chromosomes are known as:

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

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

9. Chromosomes contain heredity units called:

10. In this phase of meiosis, the bivalent line up at the equatorial plane.

11. In mitosis, the nuclear membrane is reformed and two daughter nuclei formed during:

12. The pairing of homologous chromosomes is known as:

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

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

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

16. During this phase each chromosome arranges itself on the equator of the spindle.

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

18. In the beginning of cell-division each chromosome is consist of two genetically identical copies of thread attach with each other called:

19. If the number of chromosomes in the daughter cells remains the same as in the parent cell, this type of cell division is called:

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