Answer: law of motion
Explanation:
Newton’s first two laws of motion explain how the motion of a single object changes. If the forces acting on the object are bal- anced, the object will remain at rest or stay in motion with con- stant velocity. If the forces are unbalanced, the object will accelerate in the direction of the net force. Newton’s second law tells how to calculate the acceleration, or change in motion, of an object if the net force acting on it is known.
Newton’s third law describes something else that happens when one object exerts a force on another object. Suppose you push on a wall. It may surprise you to learn that if you push on a wall, the wall also pushes on you. According to Newton’s third law of motion, 
 
        
             
        
        
        
There are four different types of nucleotides in DNA, and they differ from one another by the type of base that is present: adenine (A), thymine (T), guanine (G), and cytosine (C). A base on one of the chains that makes up DNA is chemically bonded to a base on the other chain.
