Definitions from the WebMutagenesisDefinition:Mutagenesis refers to the process of inducing mutations, usually in DNA or genetic material, which can alter the hereditary information of an organism. Senses:1. Biological MutagenesisIn the field of biology, mutagenesis involves deliberately modifying or manipulating a living organism's genetic material to study the effects of mutations on its traits or behavior. Example sentence: The scientists used mutagenesis techniques to introduce specific mutations into the fruit fly's genes and observe the resulting changes in its physical characteristics. 2. Chemical MutagenesisIn chemistry, chemical mutagenesis refers to the introduction of mutations or changes in the structure of a molecule through chemical means. Example sentence: The researchers utilized chemical mutagenesis to alter the properties of the substance and assess its effectiveness in inhibiting the growth of cancer cells. 3. Site-Directed MutagenesisSite-directed mutagenesis is a laboratory technique used to introduce specific mutations at particular sites in DNA sequences, allowing scientists to investigate the function of specific genes or regions. Example sentence: Using site-directed mutagenesis, the researchers were able to pinpoint the precise amino acid responsible for the protein's enzymatic activity. Related Products: | ||||
