What is Knockout Animals ? - Part 1- Science 8

We might confuse with these two terms:

- knockout
- Transgenic.

Transgenic is insertion of exogenous DNA into random non homologous site in the animal genome.

While Knockout is insertion of modified DNA at a specific homologous site in the animal genome.

It is interesting to discuss about knockout term furthermore in this posting.

In addition, knockout is the word commonly used to inactive an exist of specific gene in particular organism.

The way to knocked out is by replacing or disrupting the target gene with an artificial piece of DNA.

This is a genetic technique by using homologous recombination to change an endogenous gene.

Then, targeted gene could be permanent or conditional inactive or knockout.

Knockout could cause alter phenotype of organisms.

The changes might include behavior, appearance (observable physical) and biochemical characteristics of organisms.

Then, knockout organisms are used in learning about a gene that has been sequenced, which incompletely known function.

  9. A ciência está sempre em constante evolução.
    A temática é fascinante, mas é uma área acerca da qual tenho conhecimentos reduzidos.
