Indicate the stage of mitosis (interphase = I, prophase = P, metaphase = M, anaphase = A, telophase = T) during which each of the following events occur. chromatid doublets separate to individual chromosomescentriole replicatesreplicated chromosomes (chromatid doublets) are arranged in single file next to one another at the cell's equatornuclear membrane is disappearingspindle fibers form and become visiblecell plate (plant) or cleavage furrow (animal) forms and is visiblechromosomes are at opposite poles of the cell; cytokinesis is almost completedchromosomes (chromatids) first become visible as long thin strandsDNA (chromosome) replication occurs
Why would the supercoiled, condensed formof chromosomes seen in metaphase not besuitable for the G1 phase of the cell cycle?Why would the finely dispersed chromatinof the G1 phase not be suitable for mitosis?
When studying living cells in a laboratory, researchers sometimesuse drugs as a way to make cells remain at a particular stage of thecell cycle. For example, aphidicolin is an antibiotic that inhibitsDNA synthesis in eukaryotic cells and causes them to remain inthe G1 phase because they cannot replicate their DNA. In whatphase of the cell cycle—G1, S, G2, prophase, metaphase, anaphase,or telophase—would you expect somatic cells to stay if they weretreated with each of the following types of drug?A. A drug that inhibits microtubule formationB. A drug that allows microtubules to form but prevents them fromshorteningC. A drug that inhibits cytokinesisD. A drug that prevents chromosomal condensation
