CRISPER-CAS 9 Flashcards
1
Q
what does crisper stand for
A
clustered regularly interspaced short palinaromic repeats
2
Q
who introduces CRISPER
A
Jennifer Doundna and Emmanualle charpienter
3
Q
what is cas 9
A
a nucelus enzyme that also acts like mollecular scissors that are capable of cutting DNA strands
4
Q
what is the function of guide RNA
A
a chunk of RNA designed specifically to look for a complimentary segment in the DNA
5
Q
CRISPER allows researchers to
A
- modify gene function
- insert new genes
- activate genes that have been “switched off”
6
Q
using this type of technology includes
A
- curing genetic diseases
- improving crops
- gene therapy
- preventing spread of diseases
7
Q
ethical concerns raised by this type of technology
A
- it goes some religious beliefs because they believe a “potential life” has been taken away
- could edit the wrong sections of DNA which is quite rare but possible
8
Q
advantages of crisper
A
- inexpensive
- can change multiple genes at the same time
- reduces the time it takes to edit genes
9
Q
limitations of crisper -cas 9
A
- the dna can sometimes be cut in the wrong place
- unclear how specific the guide RNA’s are just for genes they are supposed to target
10
Q
current uses crisper -cas 9
A
- can alter genes
- turning a somatic cell into an embryonic-like stem cell
