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
early prophase
metaphase
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 _______. centromere
centriole 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
Telophase Late Prophase
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 _______. interphase telophase
anaphase
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
centrioles
nucleus
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
Anaphase Telophase
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
Telophase Anaphase
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
Prophase Telophase
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? Prophase Telophase
Metaphase
Anaphase
Answer: ProphaseThe prophase is the longest stage of mitosis. 13. During which stage of mitosis does longitudinal splitting of the chromosomes occur? Anaphase Prophase
Telophase
Metaphase
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.
