▼ Do they make a medicine, out of the DNA?

 No, you synthesize a medicine, like aspirin, they are purely chemical.

That means what?

That is a chemist job. We are genome, bio-chemistry, bio-genetics, molecular biology field.

If they are to identify something new in the living beings, like enzyme, like protein, can human just eating it down, to cure something?

No. Your saliva contains the enzyme itself to digest your food, do you know that? You want to eat someone else saliva? Secretion? like sweat?

No...

So you have to understand what exactly is the bio-living something create within the organism living things itself.  Your drugs is synthetically process to concentrate a particular substance, called drugs.

So I am saying don't you just extract something in the bio-living things...

Like yeast like bacteria?

If they work?

Have you heard of yeast infection and parasitic environment you drinking too acidic drinks like pop? Or have you heard that, how much yeast is in one test tubes of a incubator, to create ecoli colony, if you know the actual numbers, you will have your sense back, that is gross, Its like you are eating a snake liver, do you gonna feel better?

No.

Right.

So why don't you just use baby cells to regenerate stuffs?

That is why its called stem cell research ?

I just don't understand why they don't use other organism to mass distribute a particular extraction of proteins.

or poison.

Enzyme is not a poison. 

No. okay, do you know how to open a cell, for it to dump all the enzyme out, which enzyme is your extraction means to use? And how many cells do you need to open up and die to give all out of enzyme, you fish one by one ?

Fish one by one means?

Cells create poo, like waste all within, you open up a cell to find this cure of one enzyme, maybe 2, maybe 3. How are you planning to isolate this one thing, if you just bursts the living cell open, its EVERYTHING present to you, ALL dead in that One Single Cell !

Including DNA?

Yes. Yeast, or bacteria DNA.
