And this is just like metaphase.

So what's going to happen?

little indentation.

lot of the action is going in the nucleus.

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

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.

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

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

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 short.

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

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.

Most spiders use copious amounts of silk, and silk is essential to their survival and reproduction.

in the previous video we have already talked about the idea that there are times of earth orbit when it is closer to the sun and when it is further from the sun when it is closer to the sun

So those are my centromeres.

Coloured cotton.

Just like Moses called it.

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.

Which is best, white thread or red thread?

Which is better, red thread or white thread?

Oh, that's the storeroom for canvas and Dacron and And line.

And then you can guess what happens in anaphase Il.

So what I want to do is say to a future bug,

You did it. You did it.

To answer that, you have to look a lot closer at the spinneret region of a spider.

It starts to have a little bit of structure, and this is completely analogous to what happens in prophase 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.

Taro is writing a term paper.

It has four pairs of large eyes, curved legs, eight curved legs, and spinnerets.

I think it's important.

I got no strings to hold me do...

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.

But some of the toughest hurdles have been the technical ones.

We believe we're getting very close to something practical and affordable.

It just makes economic sense. Right now, solar paybacks are between 30 and 50 years.

Cytokinesis takes place.

Let me erase all of that.

Let me draw that there.
