  2. 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 ]

  3. CRISPR - Wikipedia

    en.wikipedia.org/wiki/CRISPR

    CRISPR-Cas can immunize bacteria against certain phages and thus halt transmission. For this reason, Koonin described CRISPR-Cas as a Lamarckian inheritance mechanism. [159] However, this was disputed by a critic who noted, "We should remember [Lamarck] for the good he contributed to science, not for things that resemble his theory only ...

  4. Evolution - Wikipedia

    en.wikipedia.org/wiki/Evolution

    Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]

  5. 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 ]

  6. Gene drive - Wikipedia

    en.wikipedia.org/wiki/Gene_drive

    Typically, scientists insert the gene drive into an organism's DNA along with the CRISPR-Cas9 machinery. When the modified organism mates and its DNA mixes with that of its mate, the CRISPR-Cas9 tool cuts the partner's DNA at the same spot where the gene drive is located in the first organism.

  8. Perturb-seq - Wikipedia

    en.wikipedia.org/wiki/Perturb-seq

    CRISPR interference (CRISPRi) on the other hand utilizes a catalytically inactive nuclease to physically block RNA polymerase, effectively preventing or halting transcription. [8] Perturb-seq has been utilized with both the knockout and CRISPRi approaches in the Dixit et al. paper [ 2 ] and the Adamson et al. paper, [ 1 ] respectively.

    The image has become better-known than the science behind it. [3] With regard to the way the illustration has been interpreted, the anthropologist and author of the section, F. Clark Howell, remarked: [6] The artist didn't intend to reduce the evolution of man to a linear sequence, but it was read that way by viewers. ...
