Gene Knockout

• The process of enhancing gene expression in an organism.

• The use of genetic engineering to inactivate or remove one or more specific genes from an organism.

• A method for cloning genes in a laboratory setting.

• The technique of inserting foreign genes into an organism.

CRISPR: a genetic engineering tool

• 
• A type of DNA sequence

• A protein that binds to RNA

Purpose of Gene Knockout

• To study the impact of removing a gene from an organism, allowing scientists to learn about that gene's function.

• To enhance the expression of a gene in an organism.

• To create genetically modified organisms with new traits.

• To identify all the genes present in an organism.
