   | Answer each question below related to mitosis, by selecting the most appropriate answer from the choices given. | 
 
 1. During which stage of mitosis is the nuclear membrane broken into fragments?
  Metaphase
  Early Prophase
  Anaphase
  Late Prophase
 
 Answer:  Early ProphaseDuring the early prophase, the nuclear membrane is broken into fragments. 2. Equatorial plate of the mitotic spindle is formed during the _______.
  anaphase
  late prophase
  metaphase
  early prophase
 
 Answer:  metaphaseDuring the metaphase, the spindle apparatus becomes well-defined and the chromosomes get arranged at the equatorial plate. 3. Mitotic cell division is initiated in the _______.
  centriole
  centromere
  nucleus
  mitotic spindle
 
 Answer:  centrioleProphase is the first phase of mitosis. It begins with the division of the centriole. 
 
 4. During which stage of mitosis do nucleoli reappear?
  Anaphase
  Early Prophase
  Late Prophase
  Telophase
 
 Answer:  TelophaseDuring the telophase, the nuclear membrane appears around the two groups of chromosomes. Thus, two well-defined nucleoli are formed. 5. The number of chromosomes in a human cell is _______.
  2
  4
  23
  46
 
 Answer:  46There are 23 pairs of chromosomes in each human cell. 6. The resting stage of the cell is known as the _______.
  telophase
  anaphase
  interphase
  prophase
 
 Answer:  interphaseThe period between two cell divisions, i.e., the resting stage of the cell, is known as the interphase. 7. During which stage of mitosis do chromatids separate to form two sets of daughter chromosomes?
  Telophase
  Prophase
  Interphase
  Anaphase
 
 Answer:  AnaphaseDuring the anaphase, the chromosomes divide at the centromere and start moving towards opposite poles. 8. Genetic information is transferred from parent to daughter cells through the _______.
  mitochondria
  endoplasmic reticulum
  nucleus
  centrioles
 
 Answer:  nucleusGenetic information is transferred from parent to daughter cells through the nucleus. 9. Which stage of mitosis is depicted in the diagram below?
 
   Metaphase
  Telophase
  Anaphase
  Prophase
 
 Answer:  AnaphaseDuring the anaphase, the chromosomes divide at the centromere and start moving towards opposite poles. Finally, they are arranged at the opposite poles of the spindle. 10. Which stage of mitosis is depicted in the diagram below?
 
   Metaphase
  Anaphase
  Telophase
  Prophase
 
 Answer:  TelophaseDuring the telophase, nuclear membrane appears around the two groups of chromosomes . Thus, two well-defined nuclei are formed. This is followed by the division of the cytoplasm by a constriction ring at the equator (in the animal cell) or by the formation of a cell plate (in the plant cell). 11. Which stage of mitosis is depicted in the diagram below?
 
   Anaphase
  Metaphase
  Telophase
  Prophase
 
 Answer:  ProphaseProphase is the first phase of mitosis. It begins with the division of centriole. Soon after the division, centrioles start moving towards the opposite poles. 12. Which of the following is the longest stage of mitosis?
  Telophase
  Metaphase
  Anaphase
  Prophase
 
 Answer:  ProphaseThe prophase is the longest stage of mitosis. 13. During which stage of mitosis does longitudinal splitting of the chromosomes occur?
  Prophase
  Telophase
  Metaphase
  Anaphase
 
 Answer:  AnaphaseDuring the anaphase, longitudinal splitting of the chromosomes occurs. 14. The interphase and mitosis together constitute the cell cycle.
  True
  False
 
 Answer:  TrueThe interphase and mitosis together constitute the cell cycle. 15. The nuclear membrane is formed around the newly-formed sets of daughter chromosomes during the telophase.
  True
  False
 
 Answer:  TrueDuring the telophase, the nuclear membrane appears around the two groups of chromosomes. Thus, two well-defined nuclei are formed. This is followed by the division of the cytoplasm by a constriction ring at the equator (in the animal cell) or by the formation of a cell plate (in the plant cell). 16. During mitosis, loosely arranged strands of chromosomes become coiled, shortened and distinct during the metaphase.
  True
  False
 
 Answer:  FalseLoosely arranged strands of chromosomes become coiled, shortened and distinct during the prophase.
