NEETBotanyCell Cycle and Cell Division
Read the following statements and choose the correct option: 1. There is no replication of DNA during interkinesis. 2. In Anaphase I, the nuclear membrane and nucleolus reappear, cytokinesis follows and this is called as triad of cells. 3. In telophase I, the homologous chromosomes separate, while sister chromatids remain associated at their centromeres. 4. Interkinesis is followed by prophase II, a much complex prop
Options
- AOnly 1 is correct
- BBoth 1 and 3 are incorrect
- CAlll are incorrect
- D2 and 4 are correct
Correct answer
A. Only 1 is correct
Step-by-step solution
In metaphase I, the bivalent chromosomes align on the equatorial plate. In Anaphase I, the homologous chromosomes separate, while sister chromatids remain associated at their centromeres. In telophase I, the nuclear membrane and nucleolus, cytokinesis follows and this is called as dyad of cells. ,Recombination between homologous chromosomes is completed by the end of Pachytene, leaving the chromosomes linked at the sites of crossing over. In oocytes of some vertebrates, diplotene can last for months or years. Diaki
