And this is an amino acid.

For example, we might say that, and this isn't the actual code, but maybe UAC, and I should look these up.

And some other ones that are not used in the set of 20, they will not appear at all in any type of concentration.

My little tRNA's pull up, pull up next to it, and they each hold a payload, right?

And these proteins, the building blocks of proteins are amino acids.

A's and G's and T's.

looking at day and night. (Laughter)

And if I have I mean, I think you get the idea.

But all of these things are proteins, and all these

And tRNA molecules are these molecules that are attached to the they're almost like the trucks for the amino acids.

So three base pairs make a codon.

So this first one holds this payload right here of this amino acid.

This codes for amino acid number 1.

It has the code AUG.

The animals can't manufacture the amino acid, lysine.

What about the lysine contingency? We could put that into effect. What's that?

It's a very long chain of these amino acids, and there are actually 20 different amino acids.

Well, three times as much, right?

Welcome to MlT. Now you're in your element.

But that's still not enough.

It's what happens in proteins.

I don't know, let's call it amino acid 1, amino acid 5, amino acid 20.

All of this stuff came from a different cell.

Well it turns out, we have many different alternatives for such a set of building blocks.

Triplets of those letters code for roughly 20 amino acids, such that there's a single letter designation for each of the amino acids.

So that we actually, to test this idea, first took a look at amino acids and some other carboxylic acids.

They'll be attached to tRNA molecules.

I really just want to give you the big picture idea of how the proteins are actually formed.

Partial Charge

Some of these are multiple chains of amino acids kind of fitting together like a big puzzle, but some of them or just single chains of amino acids.

shuts off screen Load the amino acids. I'll extract the viral DNA from his blood.

Now, genes are short segments of DNA that code for amino acids.

And this one happens to be a good source of all 20 amino acids.

It's a singlecelled protein combined with synthetic aminos, vitamins and minerals.

Of course, there is still glycine and alanine, but in fact, there are these heavy elements, these heavy amino acids, that are being produced because they are valuable to the organism.

That's still not enough to code for one of 20 amino acids to say, hey, this is going to code for amino acid number five, and we'll talk more about their actual names.

But, as we just learned, polar means that these electrons are not shared equally.

Actually, it's overkill, because we can actually have 64 combinations here, and there are only 20 amino acids, so we can even have redundant combinations code for different amino acids.

And let's say that that hydrogen is going to want to be near this oxygen.

What is one of the things that you have discovered so far? gt gt Student

What we can use are the smaller molecules that make up these proteins, the amino acids.

These positive charges are like a person's physical strength.
