How does structure of DNA ensure exact copies during replication

DNA can replicate itself because of the way its double strands relate to one another. The purines and pyrimidines that join the two strands pair exclusively with only one other base. This ensures that when the DNA strands separate to replicate an exact copy is created.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
