Cell Cycle and Cell Division MCQs 1


Question #1: Match the stages of meiosis in Column-I to their characteristic features in Column-II and select the correct option using the codes given below : Column-I Column-II a. Pachytene (i) Pairing of homologous chromosomes b. Metaphase I (ii) Terminalisation of chiasmata c. Diakinesis (iii) Crossing-over takes place d. Zygotene (iv) Chromosomes align at equatorial plate

Question #2: The number of chromosomes remain constant through successive generations due to

Question #3: Phragmoplast is

Question #4: Interzonal fibres appear in

Question #5: Metaphase II of meiosis is just like metaphase of Mitosis except

Question #6: Which stage is responsible for genetic variations and evolution of species ?

Question #7: Number of chromosome groups at equatorial plate of metaphase I of a plant having 2n = 60 chromosomes, will be

Question #8: Centrioles undergo duplication during (i) of (ii) and begin to move towards opposite poles of the cell during (iii) stage of (iv).

Question #9: Zygotic meiosis occurs in

Question #10: In an angiosperm, how many microspore mother cells are required to produce 100 pollen grains?

Question #11: A gymnosperm leaf carries 16 chromosomes. The number of chromosomes in its endosperm will be

Question #12: How many mitotic divisions are needed for a single cell to make 128 cells?

Question #13: Crossing over that results in genetic recombination in higher organisms occurs between

Question #14: Cytokinesis of a plant cell is achieved by the formation of cell plate instead of a cleavage furrow, which is formed in

Question #15: Which of the following is not the characteristics feature during mitosis in somatic cells?

Question #16: A cell at telophase stage is observed by a student in a plant brought from the field. He tells the teacher that this cell is not like the other cells in telophase stage. There is no formation of cell plate and thus the cell is containing more number of chromosomes as compared to other dividing cells. This would result in:

Question #17: When cell has stalled DNA replication fork, which checkpoint should be predominantly activated?

Question #18: At what phase of meiosis there are two cells, each with separated sister chromatids that have been moved to opposite spindle poles?

Question #19: At which stage, the homologous chromosomes separate due to repulsion, but are yet held by chiasmata?

Question #20: Diplotene stage of prophase-l is characterised by
