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

Now, once we're at this stage, each of these cells now undergo meiosis Il, which is actually very similar to mitosis.

And this is just like metaphase.

So what's going to happen?

little indentation.

lot of the action is going in the nucleus.

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.

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

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

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

And the interphase, literally it's not a phase of mitosis.

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

So the first steps that are really necessary for mitosis actually occur outside of mitosis when the cell is just doing its day to day life, and that's during the interphase.

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

Mitosis occurs in pretty much all of our somatic cells as our skin cells replicate, and our hair cells and all the tissue in our body as it duplicates itself, it goes through mitosis.

It's a germ cell.

And, of course, there's the entire cytoplasm in the rest of the cell.

But I want to make one slight clarification, that formally, mitosis only refers to the process of the replication of the genetic material and the nucleus.

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.

It's obviously got its full chromosomal complement still.

So all cells spend most of their time in interphase.

It's short.

I was there.

In a female, they would be involved in the ovaries.

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

So let me draw a germ cell.

They required scores of highly skilled weavers working over extended periods of time with very expensive materials the wools, the silks, even gold and silver thread.

She sews with a needle and thread.

And the most studied silk line of them all major ampullate silk.

Now it's going to enter metaphase Il, which is analogous to metaphase I, or metaphase in mitosis, where the chromosomes get lined up.

So let's delve into the details of how it all happens.

Here was one of the first things they built.

disabling, reversing cell cycle inhibitors.

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

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.

But just like in mitosis, one key thing does happen during the interphase, and actually, it happens during the same thing, the S phase of the interphase.

So those are my centromeres.

Coloured cotton.

Just like Moses called it.

The last stage is telophase.

Once you have each of these two cells, then they, each individually, enter their own interphase.

2,200 acres in size, 2,000 years old.

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.

When you look at this orb web, you're actually seeing many types of silk fibers.
