crispir

• • A genome editing technique called CRISPR 
• • CRISPR-Cas9 is a natural defence mechanism used by bacteria to attack invading viruses
• Scientists have manipulated this mechanism to develop a new gene editing tool. A ‘guide’ RNA sequence is developed that will match a specific complementary nucleotide sequence in a gene
• • The RNA is attached to the crispr0-cas9 enzyme and essentially guides the enzyme to the target gene allowing the gene to be cut and edited
• • This research could help treat genetic diseases by targeting specific sequences to reverse point mutations and improve targeted gene therapy.
• • It also would be a great tool for molecular biology research by improving cloning and the production of transgenic species
