crispr plustered regularly into spaced
0:02
short palindromic repeats is a gene
0:04
editing tool that allows scientists to
0:06
make precise changes to specific
0:07
locations in the genome it works by
0:10
using an enzyme called cast 9 which acts
0:12
like a pair of molecular scissors to cut
0:14
DNA at a specific location
0:16
once the DNA is cut researchers can use
0:19
crispr to either delete or replace a
0:21
section of the genome or to insert new
0:23
DNA at the site of the cut
0:25
crispr can be used to study diseases by
0:27
creating knockout models in which a
0:29
specific Gene is inactivated
0:31
for example researchers might use crispr
0:34
to delete a gene associated with a
0:35
particular disease in order to study the
0:37
effects of that Gene on the development
0:39
and progression of the disease
0:41
this can help scientists understand the
0:43
underlying mechanisms of the disease and
0:45
identify potential therapeutic targets
0:47
in addition crispr can be used to create
0:49
knock-in models in which a specific
0:51
mutation is introduced into a gene in
0:53
order to study the effects of that
0:54
mutation on disease development
