Describe how scientists use technology to determine if genes are 'turned on' or 'turned off'.

Scientists use Gene Regulation to determine if genes are on or off, Gene Regulation is the process of your body turning genes on and off. They can determine when the genes are either on or off when the brain cell acts differently from a liver or muscle cell. For example, when you walk into a different environment, your cells react quickly and adjust to the new environment. Genes are very important in our body and scientist have yet not to discover a lot about genes due to how complex it is.
