What parts of the cell cycle do you think areextended when a cell's cycle is longer? Why? Why do the other parts of the cycle not get longer?3. Compare when DNA is being replicated during the cell cycle to the amount of time the cell is performingtranscription to eventually make proteins. How many times in a cell's reproductive cycle does theduplication of DNA occur vs the amount of time the cell is transcribing the DNA. Why does this makesense with what you know about these two processes?

A cell cycle is defined as a series of events which takes place in a cell as it grows and divides. A…

When studying living cells in a laboratory, researchers sometimesuse drugs as a way to cause cells to remain in a particular phaseof the cell cycle. For example, aphidicolin inhibits DNA synthesisin eukaryotic cells and causes them to remain in the G1 phasebecause they cannot replicate their DNA. In what phase of thecell cycle—G1, S, G2, prophase, metaphase, anaphase, or telophase—would you expect somatic cells to stay if the followingtypes of drug were added?A. A drug that inhibits microtubule formationB. A drug that allows microtubules to form but prevents themfrom shorteningC. A drug that inhibits cytokinesisD. A drug that prevents chromosomal condensation
