Hello everyone.
00:05
Today we are going to discuss about crispr cas 9 and how has it influenced science since its discovery.
00:21
Okay, so let's look at it.
00:24
So what happens is that there are clusters of irregularly interspaced short palindromic repeats.
00:42
And these are your crispr, okay? crispr, which is a molecular tool, which was originally present in bacterial cells, bacterial cells.
01:00
And it acts as a bacterial defense also.
01:04
Bacterial defense.
01:09
And this is a bacterial defense against bacteriophages.
01:15
Okay.
01:15
So crispr has a protein that is associated with it, and this crispr protein is known as crispr cas9, which act as endonuclease, and it will carry the rna which is transcribed from the crispr region, and this is called as your guide rna.
01:44
So the cas9 protein, it cleaves the double standard dna molecule wherever it finds a sequence which is complementary to the guide rna sequence...
