Question

DRAW IT Draw one eukaryotic chromosome as it would appear during interphase, during each of the stages of mitosis, and during cytokinesis. Also draw and label the nuclear envelope and any microtubules attached to the chromosome(s).

Accepted Answer

Hi everyone. Our next question says identify which of the following images represents what is happening during meta phase of my topic cell division. So if I were answering this question on the test, I'd probably want to just jot down my phases of mitosis just to help me keep them straight in my mind, have them in order. I know the interphase is that phase that the cell spends most of its life in when it's not actively dividing. And then the phases of the metallic division itself start with pro phase followed by pro meta phase and then meta phase anna phase and tel Aviv's. And this is just helpful. Um So that I have that. I thought that through I have it in order and that will sort of help me approach my question when I have them all mixed up. So let's look at choice A choice A. We see chromosomes have condensed um They're paired and sister chroma tides and but they're they're not lined up or anything. And we see that spindles have formed and have connected to the central years of those chromosomes. So Choice A. Is not meta phase but it is pro meta phase beginning that process as the spindle start to attach. So choice A. Is not the correct answer. That is pro meta phase. Choice B. We see two parts of the cells the chromosomes no longer condensed, they're starting to form nuclei and the cell is sort of pinching together along the midline to form the two daughter cells that happen as a result. So we're near the end here and therefore we're at tele phase. So not meta phase, we're going to eliminate Choice B. Choice C. Shows the sister chroma tides have separated and that they are moving to the poles of the cell, so again coming towards the end. Now this is in anna face, so Choice C. Still not met a phase. Finally, we got one left choice D. And this is indeed meta phase. We have the sister chroma tied still together but all lined up along the midline of the cells with spindles attached, ready to pull apart in that next phase. So Choice D. Is what's showing us meta phase. It's the correct answer for this question. Hope to see you in the next video.
