  2. Gene knockout - Wikipedia

    en.wikipedia.org/wiki/Gene_knockout

    Gene knockout by mutation is commonly carried out in bacteria. An early instance of the use of this technique in Escherichia coli was published in 1989 by Hamilton, et al. [2] In this experiment, two sequential recombinations were used to delete the gene.

  3. Knockout mouse - Wikipedia

    en.wikipedia.org/wiki/Knockout_mouse

    The embryonic stem cells that incorporated the knocked-out gene are isolated from the unaltered cells using the marker gene from step 1. For example, the unaltered cells can be killed using a toxic agent to which the altered cells are resistant. The knocked-out embryonic stem cells from step 4 are inserted into a mouse blastocyst. For this ...

  4. Biological rules - Wikipedia

    en.wikipedia.org/wiki/Biological_rules

    Rensch's rule states that, across animal species within a lineage, sexual size dimorphism increases with body size when the male is the larger sex, and decreases as body size increases when the female is the larger sex. The rule applies in primates, pinnipeds (seals), and even-toed ungulates (such as cattle and deer). [47]

    The genetically modified mouse in which a gene affecting hair growth has been knocked out (left) shown next to a normal lab mouse. A genetically modified mouse, genetically engineered mouse model (GEMM) [1] or transgenic mouse is a mouse (Mus musculus) that has had its genome altered through the use of genetic engineering techniques.

  8. Gene silencing - Wikipedia

    en.wikipedia.org/wiki/Gene_silencing

    Methods using gene silencing are often considered better than gene knockouts [citation needed] since they allow researchers to study essential genes that are required for the animal models to survive and cannot be removed. In addition, they provide a more complete view on the development of diseases since diseases are generally associated with ...
