I'm here at the openstacks textbook, which is a copyright -free or rather an open source textbook to explain the answers to these questions.

For the first question, it mentioned what would happen, what stage of mitosis would be affected by a defect inactin.
00:19
And to understand this, we need to understand the phases of the cell cycle.
00:22
There are, there's when we get out of interphase and we go into mitosis, there are many stages that can, be seen under a microscope when we look at the chromosomes and the centrioles.
00:36
So we have prophase, pro -metaphase, we have metaphase, anephase, and telephase of cytokinesis.
00:42
So the main differences here are that in metaphase, the chromosomes are lining up here.
00:46
And in cytokinesis, after everything's all said and done, the cells actually separate.
00:52
Actin is involved in microfilament formation and in the ability of filaments to form and then and then come apart.
01:02
And so the best answer choice i would say and looking back at your answer or the answer choices real is if you decrease the, if you have a drug that decreases the function of actin, you're going to have a problem in anaphaise, the separation of chromosomes in this particular, in animal cells...
