  2. CRISPR - Wikipedia

    en.wikipedia.org/wiki/CRISPR

    CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.

  3. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    CRISPR-Cas9. CRISPR gene editing (CRISPR, pronounced / ˈ k r ɪ s p ə r / "crisper", refers to "clustered regularly interspaced short palindromic repeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial CRISPR-Cas9 antiviral ...

  4. Cas9 - Wikipedia

    en.wikipedia.org/wiki/Cas9

    IPR028629. Cas9 (CRISPR associated protein 9, formerly called Cas5, Csn1, or Csx12) is a 160 kilodalton protein which plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids, and is heavily utilized in genetic engineering applications. Its main function is to cut DNA and thereby alter a cell's genome.

  5. CRISPR interference - Wikipedia

    en.wikipedia.org/wiki/CRISPR_interference

    CRISPR interference (CRISPRi) is a genetic perturbation technique that allows for sequence-specific repression of gene expression in prokaryotic and eukaryotic cells. [1] It was first developed by Stanley Qi and colleagues in the laboratories of Wendell Lim , Adam Arkin, Jonathan Weissman , and Jennifer Doudna . [ 2 ]

  6. CRISPR activation - Wikipedia

    en.wikipedia.org/wiki/CRISPR_activation

    CRISPR activation (CRISPRa) is a gene regulation technique that utilizes an engineered form of the CRISPR-Cas9 system to enhance the expression of specific genes without altering the underlying DNA sequence. Unlike traditional CRISPR-Cas9, which introduces double-strand breaks to edit genes, CRISPRa employs a modified, catalytically inactive ...

  7. Emmanuelle Charpentier - Wikipedia

    en.wikipedia.org/wiki/Emmanuelle_Charpentier

    Charpentier is best known for her Nobel-winning work of deciphering the molecular mechanisms of a bacterial immune system, called CRISPR/Cas9, and repurposing it into a tool for genome editing. In particular, she uncovered a novel mechanism for the maturation of a non-coding RNA which is pivotal in the function of CRISPR/Cas9.
