And then you can guess what happens in anaphase Il.

I think it's important.

Cytokinesis takes place.

Now, during the S phase of the interphase and this is just

Of course, this is all one cell.

And this is just like metaphase.

So what's going to happen?

little indentation.

And then in meiosis 2, these things get split in a mechanism very similar to mitosis.

lot of the action is going in the nucleus.

So this is mitosis.

We'll do a whole series of videos on the actual mechanics of that, but it splits by a mechanism called mitosis.

We haven't entered the actual cell division yet.

And the same thing is true and this is kind of a little bit of a sideshow of the centrosomes.

Now, those are separated, which is very similar to anaphase in mitosis.

It's in its chromatin form.

And then the second phase separated the sister chromatids, just like what happens in mitosis.

like what happens in mitosis, so you can almost view it as it always happens during interphase.

little bit more in detail.

Now, we're ready for mitosis.

And so by the end of the telophase that's what we're in, the telophase we will have completed mitosis.

So, hopefully, you found that interesting.

But if you've got a teacher that likes to get you on a technicality, this is technically what mitosis is.

Now, anaphase I is interesting, because remember, in mitosis in anaphase, the actual chromatids, the sister chromatids separated from each other.

Now, I'm going to be a little careful here.

Now, with that said, let's go into the mechanics of mitosis.

So this is all occurring in the interphase, and particularly in the S part of the interphase, not the growth part.

Now, most of these cells of this human being, if this is me or you, these are all the product of mitosis that started off with that zygote, and it just kept dividing and dividing and dividing into mitosis.

It's a germ cell.

And some of them, as we learned, this is exactly what happened in mitosis.

So this is cytokinesis, which is formally not a part of mitosis, but it normally occurs with the telophase, so right at the end of mitosis, you do normally have two complete identical cells.

And this is all happening as they keep replicating.

And formally, mitosis is really the process of the duplication of the nucleus, but it normally ends up with two entire cells.

And S is where you have replication of the actual chromosomes.

That's normally accompanied by cytokinesis where the cytoplasms of the cells actually separate.

I've already done a video on mitosis, and in this one, we'll go into the details of meiosis.

Sometimes it's considered I don't think there's a hyphen really there.

So let me draw a germ cell.

You're not actually splitting the chromosomes into their constituent chromatids, and that's key.

And I'm going to draw it as chromosomes, but you have to remember that when we're outside of mitosis or meiosis formally, the chromosomes are all unwound, and they exist as chromatin, which we've talked about before.

We have a video on it where we go into the phases of it prophase, metaphase, anaphase and telophase.

Interphase is just a time when the cell is living and transcribing and doing what it needs to do.

Of course, all of this is occurring within the cell and these are getting pulled apart.

At some point, these two things are going to replicate, and that's the S phase, and you go to the G2 phase, and then this guy will experience mitosis all over again.
