  2. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    CRISPR-Cas9 genome editing techniques have many potential applications. The use of the CRISPR-Cas9-gRNA complex for genome editing [10] was the AAAS's choice for Breakthrough of the Year in 2015. [11] Many bioethical concerns have been raised about the prospect of using CRISPR for germline editing, especially in human embryos. [12]

  3. Genome-wide CRISPR-Cas9 knockout screens - Wikipedia

    en.wikipedia.org/wiki/Genome-wide_CRISPR-Cas9...

    The approach utilises the CRISPR-Cas9 gene editing system, coupled with libraries of single guide RNAs (sgRNAs), which are designed to target every gene in the genome. Over recent years, the genome-wide CRISPR screen has emerged as a powerful tool for performing large-scale loss-of-function screens, with low noise, high knockout efficiency and ...

  4. CRISPR/Cas tools - Wikipedia

    en.wikipedia.org/wiki/CRISPR/Cas_Tools

    For a given candidate gRNA, these tools report its list of potential off-targets in the genome thereby allowing the designer to evaluate its suitability prior to embarking on any experiments. Scientists have also begun exploring the mechanics of the CRISPR/Cas system and what governs how good, or active, a gRNA is at directing the Cas nuclease ...

  5. CRISPR - Wikipedia

    en.wikipedia.org/wiki/CRISPR

    Cas9 enzymes together with CRISPR sequences form the basis of a technology known as CRISPR-Cas9 that can be used to edit genes within living organisms. [ 9 ] [ 10 ] This editing process has a wide variety of applications including basic biological research, development of biotechnological products, and treatment of diseases.

  6. Gene editing - Wikipedia

    en.wikipedia.org/wiki/Gene_editing

    TALEN editing, using transcription activator-like effector nucleases. TALENs are another type of genome editing tool. They work by using engineered proteins that can recognize and bind to specific DNA sequences, which then triggers a cut in the DNA. TALENs are less efficient than CRISPR/Cas9, but they are still a useful tool for genome editing.

  7. Human genetic enhancement - Wikipedia

    en.wikipedia.org/wiki/Human_genetic_enhancement

    The CRISPR/Cas9 system is also designed as a gene editing technology for the treatment of HIV-1/AIDS. CRISPR/Cas9 has been developed as the latest gene editing technique that allows the insertion, deletion and modification of DNA sequences and provides advantages in the disruption of the latent HIV-1 virus.

  8. CRISPR activation - Wikipedia

    en.wikipedia.org/wiki/CRISPR_activation

    Complementary base pairing between the sgRNA and genomic DNA allows targeting of Cas9 or dCas9. A small guide RNA (sgRNA), or gRNA is an RNA with around 20 nucleotides used to direct Cas9 or dCas9 to their targets. gRNAs contain two major regions of importance for CRISPR systems: the scaffold and spacer regions.

  9. Human germline engineering - Wikipedia

    en.wikipedia.org/wiki/Human_germline_engineering

    The CRISPR-Cas9 system consists of an enzyme called Cas9 and a special piece of guide RNA (gRNA). Cas9 acts as a pair of ‘molecular scissors’ that can cut the DNA at a specific location in the genome so that genes can be added or removed.
