Let's talk about another gene editing two that comes from bacteria.
00:08
This time we're talking about crispr cas 9.
00:26
So crispr cas 9, which is short for, and i won't write it all the way out because it's short for a very long thing.
00:34
Clustered regularly interspaced short palindromic repeats and crispr associated protein 9.
00:44
I told you it was long.
00:45
Now crispr, again, stems from bacteria.
01:05
And so what happens is that bacteria can actually capture dna from viruses.
01:22
And they use this to create what's known as crispr arrays.
02:24
Now, these arrays allow for bacteria to remember viruses.
02:32
So it's kind of like an immune system or immunological type response.
02:38
So, and with that being said, if the same virus tries to attack again, the bacteria can use the enzyme called cas9 or crispr associated protein 9 to cut the dna apart, which disables the virus...
