Usage: technical; biology and chemistry

Examples

• Photoinduction of gene expression allows plants to respond to changes in light intensity.
• The researcher studied photoinduction in bacterial cells exposed to ultraviolet radiation.
• Photoinduction of the lac operon in certain microorganisms demonstrates how light can regulate metabolism.
• The photoinduction process is critical for the organism's ability to synthesize protective pigments.
• Scientists use photoinduction techniques to control protein production in laboratory experiments.
