Chemical genetics is a field that combines chemistry and genetics to study biological processes. It involves using small molecules, or chemical compounds, to manipulate and understand the functions of genes and proteins. By observing how these compounds affect cellular behavior, researchers can gain insights into gene function and disease mechanisms. This approach allows scientists to identify potential drug targets and develop new therapies. For example, small molecules can be designed to inhibit specific proteins involved in diseases like cancer or neurodegenerative disorders. Overall, chemical genetics provides valuable tools for exploring the complexities of biological systems.
