2. Genome editing technology
• Genome editing (also called gene editing) is a group
of technologies that give scientists the ability to
change an organism's DNA.
• These technologies allow genetic material to be
added, removed, or altered at particular locations
in the genome.
• A method for making specific changes to the DNA
of a cell or organism.

5. Cont
• CRISPR/Cas9 edits genes by precisely cutting DNA
and then letting natural DNA repair processes to
take over.
• The system consists of two parts: the Cas9 enzyme
and a guide RNA.
• A laboratory tool used to change or “edit” pieces of
a cell's DNA.

6. Cont
• CRISPR-Cas9 has been commonly used to create
gene editing in plants, animal, and human samples.
• This technique is widely used in various scientific
fields, including medical science and therapeutics,
as well as plant and animal sciences

• Gene therapy is a technique that modifies a
person's genes to treat or cure disease.
• Gene therapy holds promise for treating a wide
range of diseases, such as cancer, cystic fibrosis,
heart disease, diabetes, hemophilia and AIDS.

19. Cont
• Gene transfer is a new treatment modality that
introduces new genes into a cancerous cell or the
surrounding tissue to cause cell death or slow the
growth of the cancer.
• This treatment technique is very flexible, and a
wide range of genes and vectors are being used in
clinical trials with successful outcomes.
