the role of DNA  
Without the inheritance of DNA, people are a mere darkness without a purpose or hope. If the inheritance of DNA were to halt, there may still be people on the earth, but the people would lack adaptability, survival skills, uniqueness, and individualism. Eventually, the people could become extinct. Therefore, it is important to know that DNA and its' role of replicating, repairing, and transmitting genetic information to the cells of the body preserves and continues the life cycle.
