This is known as mutagenesis. This can be achieved in a number of ways, in either a controlled or random manner. Random mutagenesis can be achieved through exposure to UV light or free radicals such as hydrogen peroxide, which would create different mutations in each cell. Controlled mutagenesis can be performed to ensure that all organisms (single- or multi-celled) have the same genetic makeup. One method to modify DNA in a controlled manner involves the use of modified viruses.

Mutations. The method of treating defective or faulty genes is called gene therapy.

What do biologists study?

A biologist is a scientist devoted to and producing results in biology through the study of life. Typically biologists study organisms and their relationship to their environment. Biologists involved in basic research attempt to discover underlying mechanisms that govern how organisms work. Biologists involved in applied research attempt to develop or improve medical, industrial or agricultural processes.
