Alright. So here we have an example problem that's asking why cytokinesis is an important part of cell division. After reading through each of these four answer options down below, there are a few that we can eliminate right off the bat. Taking a look at option D down below, it says that cytokinesis is responsible for the growth and production of new organelles and other cytoplasmic contents. But of course, we know that this is not the role of cytokinesis; this option, option D, is more so the role of interphase.

But interphase and cytokinesis are not the same thing. So we can go ahead and cross off answer option D. Answer option C says that cytokinesis is responsible for the linking of two sister chromatids, but of course, that's not going to be the case at all. That's not what we discussed in our previous lesson videos. And so now we're between answer option A and answer option B, and notice answer option A says that cytokinesis is responsible for the proper separation of genetic information.

But technically, it's mitosis that is separating the genetic information, which is the DNA, and separating the single nucleus to form two nuclei. And so really, it's mitosis that is responsible for the proper separation of the genetic information. Mitosis is slightly different from cytokinesis, and so option A is more so linked to mitosis, not cytokinesis. And so, of course, this only leaves answer option B here as the correct answer and so cytokinesis is an important part of cell division because it is responsible for the proper separation of the cytoplasmic contents, and that's really how cytokinesis is defined as the division of the cytoplasm. And so, answer option B here is going to be the correct answer for this example problem and that concludes this example, so I'll see you all in our next video.
