  2. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    CRISPR may be used at the germline level to create organisms in which the targeted gene is changed everywhere (i.e. in all cells/tissues/organs of a multicellular organism), or it may be used in non-germline cells to create local changes that only affect certain cell populations within the organism.

  3. CRISPR activation - Wikipedia

    en.wikipedia.org/wiki/CRISPR_activation

    One research group used a system in which dCas9 was fused to a particular domain, C1B1. When blue light is shined on the cell, the cryptochrome 2 (Cry2) domain binds to C1B1. The Cry2 domain is fused to a transcriptional activator , so blue light targets the activator to the spot where dCas9 is bound.

  4. CRISPR-associated transposons - Wikipedia

    en.wikipedia.org/wiki/CRISPR-associated_transposons

    CRISPR-associated transposons or CASTs are mobile genetic elements that have evolved to make use of minimal CRISPR systems for RNA-guided transposition of their DNA. [1] Unlike traditional CRISPR systems that contain interference mechanisms to degrade targeted DNA, CASTs lack proteins and/or protein domains responsible for DNA cleavage. [ 2 ]

  5. 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.

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

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

    The exact protocol for lentiviral production will vary depending on the research aim and applied library. [35] [43] [44] If a two vector-system is used, for example, cells are sequentially transduced with Cas9 and sgRNA in a two-step procedure. [35] [44] Although more complex, this has the advantage of a higher titre for the sgRNA library virus ...

    en.wikipedia.org/wiki/Emmanuelle_Charpentier

    In 2018, she founded an independent research institute, the Max Planck Unit for the Science of Pathogens. [3] In 2020, Charpentier and American biochemist Jennifer Doudna of the University of California, Berkeley, were awarded the Nobel Prize in Chemistry "for the development of a method for genome editing" (through CRISPR). This was the first ...

  8. CRISPR RNA - Wikipedia

    en.wikipedia.org/wiki/CRISPR_RNA

    CRISPR RNA or crRNA is a RNA transcript from the CRISPR locus. [1] CRISPR-Cas (clustered, regularly interspaced short palindromic repeats - CRISPR associated systems) is an adaptive immune system found in bacteria and archaea to protect against mobile genetic elements , like viruses , plasmids , and transposons . [ 2 ]

  9. Guide RNA - Wikipedia

    en.wikipedia.org/wiki/Guide_RNA

    The RNA editing guide RNA was discovered in 1990 by B. Blum, N. Bakalara, and L. Simpson through Northern Blot Hybridization in the mitochondrial maxicircle DNA of the eukaryotic parasite Leishmania tarentolae. Subsequent research throughout the mid-2000s and the following years explored the structure and function of gRNA and the CRISPR-Cas system.
