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
