Restriction enzyme

  • Gel electrophoresis is a process or a technique in which fragments of DNA  are separated in terms of their sizes.

kolezko [41]
It depends on the individual reaction to lactose. first, some individuals are considered lactose intolerant meaning they lack enzymes that break down lactose into glucose and galactose. hence, if they digest dairy products they can have severe symptoms that will affect their health. however individual who aren’t lactose intolerant benefit from digesting lactose containing products because it improves the individuals health by providing the body with sufficient amount of energy when lactose is broken down to glucose and galactose. Also, consuming Foods in the Dairy Group provide nutrients that are vital for health and maintenance of the body. over all, it all comes down to how an individual will react to such decisions when eliminating lactose. If this decision outweighs the disadvantages then I agree with it however if it doesn’t I completely disagree
