  2. CRISPR/Cas tools - Wikipedia

    en.wikipedia.org/wiki/CRISPR/Cas_Tools

    CRISPR-Cas design tools are computer software platforms and bioinformatics tools used to facilitate the design of guide RNAs (gRNAs) for use with the CRISPR/Cas gene editing system. CRISPR-Cas [ edit ]

  3. 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]

  4. CRISPR activation - Wikipedia

    en.wikipedia.org/wiki/CRISPR_activation

    Unlike traditional CRISPR-Cas9, which introduces double-strand breaks to edit genes, CRISPRa employs a modified, catalytically inactive Cas9 (dCas9) fused with transcriptional activators to target promoter or enhancer regions, thereby boosting gene transcription. This method allows for precise control of gene expression, making it a valuable ...

  5. Cas9 - Wikipedia

    en.wikipedia.org/wiki/Cas9

    Cas9 has been used often as a genome-editing tool. Cas9 has been used in recent developments in preventing viruses from manipulating hosts' DNA. Since the CRISPR-Cas9 was developed from bacterial genome systems, it can be used to target the genetic material in viruses. The use of the enzyme Cas9 can be a solution to many viral infections.

  6. 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.

  7. Guide RNA - Wikipedia

    en.wikipedia.org/wiki/Guide_RNA

    The cas9 complex, illustrating the gRNA, PAM and the double-stranded break induced in the target DNA. CRISPR (Clustered regularly interspaced short palindromic repeats)/Cas9 is a technique used for gene editing and gene therapy. Cas is an endonuclease enzyme that cuts DNA at a specific location directed by a guide RNA.

  8. Site-directed mutagenesis - Wikipedia

    en.wikipedia.org/wiki/Site-directed_mutagenesis

    Site-directed mutagenesis is a molecular biology method that is used to make specific and intentional mutating changes to the DNA sequence of a gene and any gene products. Also called site-specific mutagenesis or oligonucleotide-directed mutagenesis , it is used for investigating the structure and biological activity of DNA , RNA , and protein ...

  9. 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 ...
