Answer:
Cytokinesis
Step-by-step explanation:
We can prove Cytokinesis to be the correct answer because Mitosis occurs over a period of 2 hours, Interphase occurs over a period between 18 and 20 hours and Cytokinesis only occurs over a period about an hour long. Comparing between these numbers we can clearly see 1 hour is less than 2 hours, and 18-20 hours. Since Cytokinesis is the shortest stage of the cell cycle we can rule out all the other answers expect for B. Cytokinesis.
What is Mitosis?
Mitosis is a process of cell duplication, in which one cell divides into two genetically identical daughter cells. In the various stages of mitosis, the cell's chromosomes are copied and then distributed equally between the two new nuclei of the daughter cells. This process of cell duplication takes about 2 hours.
What is Cytokinesis?
Cytokinesis means the process of division of cytoplasm. Division. The nucleus gets divided into two daughter nuclei. The cytoplasm, cell organelles and the nuclei divide and are passed on to daughter cells equally. This process of division of cytoplasm takes about 1 hour.
What is interphase?
Interphase refers to the phase of the cell cycle in which a cell copies its DNA to prepare for mitosis. This phase is also referred to as the 'daily living' or the metabolic phase of the cell. Furthermore, in this stage, a cell gets nutrients and then metabolizes these nutrients. The process of Interphase takes about 18-20 hours.
