During the M-phase (Mitosis), spindle fibers extend from centrioles in the poles of the cell and attach to the centromeres of each replicated chromosome. The chromosomes are aligned along the equatorial plate of the cell in the process. Once all centromeres got attached from either side to a spindle fibre, a cellular checkpoint got passed and the spindle fibers begin to contract towards the poles, pulling the two sister chromatids apart such that one sister chromatid of each of the...

A Which of the following does NOT occur during mitosis? condensation of the chromosomes replication of the DNA spindle formation separation of sister chromatidsB. Which of the following statements regarding the function of mitosis is false? Mitosis promotes genetic diversity. Mitosis is necessary for asexual reproduction in eukaryotes. Mitosis promotes repair tissues. Mitosis allows organisms to grow.C. At the end of which phase of cell division are the daughter cells half the ploidy (n) of the original parent cell (2n)? after Mitosis after Mitosis and MeiosisⅠafter MeiosisⅠafter Meiosis II

all these questions have more than one correct answers 1) Meiosis & mitosis have similarities as well as differences. Which of the following represent similarities? a) Both increases genetic variation b) Both change in chromosomes number in daughter cells c) Both only occur in eukaryotes D) DNA replication must occur prior to both e) Both make use of a spindle to separate chromatids 2) Meiosis is a special form of cell division. Select any of the following that applies to...
Match the stage of mitosis with the correct description.
Match the stage of mitosis with the correct description.a. Microtubles that are attached to each chromosome shorten, pulling the sister chromatids apart.b. The chromosomes line up single file in the middle of the cell. Sister chromatids are clearly visible in this stage.c. The chromosomes that were pulled apart reach their respective poles. The chromosomes decondense. The nuclear envelope re-forms. The cytoplasm with organelles divides.d. Chromosomes have replicated and appear as an "X". The nuclear envelope begins to break down. The...
