MCQs
Q1. In which phase of the cell cycle is DNA replicated?
(a) G1 phase
(b) G2 phase
(c) S phase
(d) M phase
Show Answer
Answer: (c)
Explanation: DNA replication occurs during the S (synthesis) phase of the interphase.
Q2. What is the primary checkpoint that ensures cell readiness for DNA synthesis?
(a) G0 checkpoint
(b) G1 checkpoint
(c) G2 checkpoint
(d) Metaphase checkpoint
Show Answer
Answer: (b)
Explanation: The G1 checkpoint verifies if the cell is ready for DNA replication.
Q3. Which of the following is not a component of the mitotic spindle?
(a) Microtubules
(b) Centrosomes
(c) Actin filaments
(d) Kinetochores
Show Answer
Answer: (c)
Explanation: Actin filaments are involved in cytokinesis, not spindle formation.
Q4. Which phase is characterized by chromatin condensation and spindle formation?
(a) Prophase
(b) Metaphase
(c) Anaphase
(d) Telophase
Show Answer
Answer: (a)
Explanation: In prophase, chromatin condenses and the spindle apparatus begins to form.
Q5. Which protein regulates cell cycle checkpoints?
(a) Histone
(b) Tubulin
(c) Cyclin
(d) Actin
Show Answer
Answer: (c)
Explanation: Cyclins regulate the progression of cells through the cell cycle.
Q6. Which stage of mitosis ensures that sister chromatids separate?
(a) Prophase
(b) Anaphase
(c) Telophase
(d) Metaphase
Show Answer
Answer: (b)
Explanation: In anaphase, sister chromatids are pulled toward opposite poles.
Q7. What happens during cytokinesis in plant cells?
(a) Cleavage furrow forms
(b) Golgi vesicles form the cell plate
(c) Cell membrane pinches
(d) Centrioles duplicate
Show Answer
Answer: (b)
Explanation: In plant cells, cytokinesis occurs by formation of a cell plate from Golgi vesicles.
Q8. Which of the following cells is likely to stay in G0 phase permanently?
(a) Skin cells
(b) Nerve cells
(c) Liver cells
(d) Muscle cells
Show Answer
Answer: (b)
Explanation: Nerve cells typically remain in G0 and do not divide again.
Q9. Which checkpoint ensures that chromosomes are properly attached to spindle fibers?
(a) G1 checkpoint
(b) G2 checkpoint
(c) S checkpoint
(d) Metaphase checkpoint
Show Answer
Answer: (d)
Explanation: The metaphase checkpoint ensures all chromosomes are aligned and attached to spindles.
Q10. Why is meiosis II called equational division?
(a) Because it reduces chromosome number
(b) Because sister chromatids separate
(c) Because DNA replicates again
(d) Because homologous chromosomes pair
Show Answer
Answer: (b)
Explanation: Meiosis II separates sister chromatids, maintaining chromosome number.
Q11. What would happen if the spindle fibers failed to form during mitosis?
(a) Chromosomes would not replicate
(b) Cytokinesis would not occur
(c) Chromosomes wouldn’t separate
(d) Cell membrane would break
Show Answer
Answer: (c)
Explanation: Without spindle fibers, chromosomes cannot separate to opposite poles.
Q12. In which phase of meiosis does crossing over occur?
(a) Prophase I
(b) Metaphase I
(c) Anaphase I
(d) Prophase II
Show Answer
Answer: (a)
Explanation: Crossing over occurs during prophase I of meiosis, leading to genetic variation.
Q13. Which structure forms during animal cell cytokinesis but not in plant cells?
(a) Cell plate
(b) Cleavage furrow
(c) Spindle apparatus
(d) Centrioles
Show Answer
Answer: (b)
Explanation: Animal cells form a cleavage furrow, unlike plant cells which form a cell plate.
Q14. Which process ensures genetic variability during meiosis?
(a) DNA replication
(b) Crossing over
(c) Cytokinesis
(d) Telophase
Show Answer
Answer: (b)
Explanation: Crossing over shuffles alleles, ensuring genetic diversity in gametes.
Q15. In which stage of meiosis are homologous chromosomes separated?
(a) Anaphase I
(b) Anaphase II
(c) Metaphase I
(d) Telophase II
Show Answer
Answer: (a)
Explanation: Anaphase I separates homologous chromosomes while chromatids remain attached.
Q16. Which phase of cell division is the longest?
(a) M phase
(b) S phase
(c) G1 phase
(d) G2 phase
Show Answer
Answer: (c)
Explanation: G1 phase is generally the longest in duration in actively dividing cells.
Q17. What initiates the cell to enter mitosis from G2?
(a) Spindle checkpoint
(b) MPF (Maturation Promoting Factor)
(c) Cyclin D
(d) Telomerase
Show Answer
Answer: (b)
Explanation: MPF triggers the cell’s entry into mitosis from G2.
Q18. What ensures that each daughter cell gets the same number of chromosomes?
(a) Random segregation
(b) Spindle checkpoint
(c) Apoptosis
(d) Crossing over
Show Answer
Answer: (b)
Explanation: Spindle checkpoint prevents missegregation of chromosomes.
Q19. Which feature is unique to meiosis but absent in mitosis?
(a) Chromosome condensation
(b) Cytokinesis
(c) Homologous chromosome pairing
(d) Spindle formation
Show Answer
Answer: (c)
Explanation: Homologous chromosome pairing and crossing over occur only in meiosis.
Q20. How many daughter cells result from meiosis and are they genetically identical?
(a) 2, identical
(b) 2, different
(c) 4, identical
(d) 4, different
Show Answer
Answer: (d)
Explanation: Meiosis produces 4 genetically different haploid daughter cells.
