CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a gene editing technology that uses a small RNA molecule to locate and edit specific genes. This technology has revolutionized the field of genetics, enabling scientists to study gene function, develop new treatments for genetic diseases, and even edit genes in human embryos. CRISPR works by using a small RNA molecule, known as a guide RNA, to locate a specific sequence of DNA. An enzyme, known as Cas9, then cuts the DNA at this site, allowing scientists to edit the gene by inserting or deleting nucleotides.
