Question
The second meiotic division is essentially a mitosis division except for the fact that a. haploid. b. diploid. c. polyploid. d. autosomal. e. somatic. In mitosis, the chromosomes are lined up on the equator during ______. a. interphase b. prophase c. metaphase d. anaphase e. telophase If the total number of chromosomes in a cell is 6, then after mitosis there will be a. 6 chromosomes in each daughter cell. b. 3 chromosomes in each daughter cell. c. 12 chromosomes in each daughter cell. d. 3 chromosomes in one daughter cell and 6 chromosomes in the other e. 2 chromosomes in each daughter cell. During ______, daughter chromosomes are widely separated having moved distance from the equatorial plate. a. interphase b. prophase c. metaphase d. anaphase e. telophase The nuclear membrane reappears in mitosis during ______. a. interphase b. prophase c. metaphase d anaphase e. telophaseExplanation / Answer
Please find the answers and explanations below:
Answer 3: Choice a (The meiosis contains two phases, first and second. The second phase is just like mitosis except that the daughter cells produced in it are haploid in nature)
Answer 4: Choice c (Metaphase is the phase of cell cycle in which the condensed chromosomes lie across the equator of the spindle fibre in the cell. The other phases of cell cylce include either dissolution or terminal localization of the chromosomes)
Answer 5: Choice a (Mitosis is normal cellular division in which the chromosomes number remains same in the daughter cells like the parent cell. Unlike meiosis which is reductional division, the number of chromsomes does not reduces to half in mitosis)
Answer 6: Choice d (Anaphase is the phase of cell cycle in which the chromosomes move to the spindle poles due to strething of the spindle fibres and start for division of the cell across the equator)
Answer 7: Choice b (The nuclear membrane dissolves during early phase of cell cycle i.e. prophase. During this phase, the chromosomes become enlarge and lie in the cytoplasm only.)
