  2. CRISPR - Wikipedia

    en.wikipedia.org/wiki/CRISPR

    The system has 2 CRISPR loci and 9 Cas genes. It seems to be homologous to the I-F system found in Yersinia pestis. Moreover, like the bacterial CRISPR-Cas system, ICP1 CRISPR-Cas can acquire new sequences, which allows phage and host to co-evolve. [177] [178] Certain archaeal viruses were shown to carry mini-CRISPR arrays containing one or two ...

  3. 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 ...

  4. 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 a 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 ...

  5. 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.

    This meeting was the beginning of the "cognitive revolution"—an interdisciplinary paradigm shift in psychology, philosophy, computer science and neuroscience. It inspired the creation of the sub-fields of symbolic artificial intelligence , generative linguistics , cognitive science , cognitive psychology , cognitive neuroscience and the ...

  7. 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 ]

    Lotfi A. Zadeh at U.C. Berkeley creates "soft computing" [84] and builds a world network of research with a fusion of neural science and neural net systems, fuzzy set theory and fuzzy systems, evolutionary algorithms, genetic programming, and chaos theory and chaotic systems ("Fuzzy Logic, Neural Networks, and Soft Computing", Communications of ...

  9. 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 .
