In Vitro Mutagenesis for Gene Analysis

In vitro mutagenesis is a lab method used to change DNA and study gene function. It helps scientists test how specific DNA changes affect a gene’s activity and the traits it controls.

A common approach is to make a known change in a DNA sequence and then examine the result. This can be done by de...

Scientists can inactivate or knock out a gene in animals, commonly mice, to learn more about the function of the gene, usually by replacing it with a targeting vector, an engineered piece of DNA.

The targeting vector has sequences that are homologous, identical to the sequences before and after the gene. It usually also has a positive se...
