5 Facts you should know about
CRISPR
1
CRISPRs were first discovered by Francisco Mojica, a scientist at the University of Alicante in Spain
2
CRISPRs work by harnessing the natural mechanisms of the immune systems of bacterium cells of invading viruses, which is then able to cut out infected DNA strands
3
CRISPR “spacer” sequences are transcribed into short RNA sequences that are capable of guiding the system to matching sequences of DNA
4
When the target DNA is found, Cas9 – one of the enzymes produced by the CRISPR system – binds to the DNA - and cuts it
5
Using modified versions of Cas9, researchers can then activate expression of targeted genes
