Abstract:
The dominant selective markers that we and others have constructed for the selection of cells which stably acquired a foreign DNA, are briefly described. The possibility of obtaining the cointegration of several genes, and of inducing their amplification in the recipient cell, is discussed.

Overview
In-vitro Mutagenesis
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
