So those are my centromeres.

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

Let me erase all of that.

Let me draw that there.

And, of course, they're being aligned.

Now, this is happening in two cells, of course.

Climb again over the course of 24 hours.

Those are centromeres.

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

This is the dragline spun by scytodes, the spitting spider.

It's short.

Domitia, Domitia, and Domitia are tasked with spinning the wool that will be used to weave this mighty garment, 30 or more feet long and elliptical in shape.

She sews with a needle and thread.

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

To artificially produce spider silk with the help of genetically modified microbes and weave it as synthetic fiber, is our idea.

Coloured cotton.

Just like Moses called it.

I think it's important.

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.

You did it. You did it.

Like a string between two tin cans. You know what's great about that is that it's completely insane?

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

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

It'll protect you.

Of course, this is all one cell.

I got no strings to hold me do...

But you put one hand in each hairband and attach that hairband, we tied a fishing line.

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

Tom attached the string to the kite.

Oxalic acid is two carbon dioxide molecules joined together.

And the horse is made from nylon.

Do you see that blind thread that missed the weave and lies on top of the others?

Cytokinesis takes place.

Why on earth are you crocheting a reef?

50 Vicryl.

The frame and radii of this web is made up of one type of silk, while the capture spiral is a composite of two different silks the filament and the sticky droplet.

You can see multiple fibers coming out of the spinnerets, because each spinneret has many spigots on it.

Pyriform silk glands make the attachment cement that's the silk that's used to adhere silk lines to a substrate.

Nye So what's this right here?

We do chemistry in organic solvents.

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