Which of the following statements correctly describes an event that occurs during mitotic karyokinesis?
Options
- AHomologous chromosomes separate, while sister chromatids remain associated at their centromeres.
- BChromosomes cluster at opposite spindle poles and their identity is lost as discrete elements.
- CBivalents align on the equatorial plate and spindle fibres attach to the kinetochores of homologous chromosome
- DRecombination nodules appear and exchange of genetic material occurs between non-sister chromatids.
Correct answer
B. Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements.
Step-by-step solution
Mitotic karyokinesis involves four stages: prophase, metaphase, anaphase, and telophase. Option (A) describes anaphase I of meiosis, where homologous chromosomes separate but sister chromatids remain attached at their centromeres. Option (B) describes telophase of mitosis, where chromosomes reach the opposite poles, decondense, and lose their individuality as discrete elements. Option (C) describes metaphase I of meiosis, where bivalents (homologous chromosome pairs) align at the equatorial plate. Option (D) descri
