Respuesta :

the following are the environmental factors that can damage genes that code for these enzymes. radiation from sun, various chemicals and x-rays. these agents are referred to as environmental mutagens. they result to changes in the genetic make up of the organism and in  turn affect the production of enzymes. enzymes are protein in nature and once the DNA has been compromised their production is affected. in most cases mutated DNA produces enzymes with lost or abnormal function.

Answer:

1. UV rays.

2.  X-rays.

3. Chemical agents. Example Ethidium bromide.

Explanation:

Three environmental factors that can damage the genes that produce those enzymes include UV rays, X-rays and chemical agents. These agents are called mutagens. When an organism is exposed to these agents, they alter the cells DNA resulting to changes in the genetic makeup of the organism and in turn affect the production of enzymes. Enzymes are proteins, and once the DNA is affected, their production is inhibited. In most cases, mutated DNA  produces enzymes with poor or abnormal function.
