DNA and RNA both are the types of nucleic acids.

• DNA (Deoxyribonucleic acid) store the genetic  information.

• RNA (Ribonucleic acid) helps in protein synthesis. It carry and translates the genetic codes.

Magnetism is the force exerted by a magnet. It comes when the magnet attracts or repulses an object. For example, a magnet sticks to certain objects because the magnetic force or magnetism pulls it.

There are three main processes Isothermal, adiabatic and cyclic process. In isothermal, the system is thermally conductive and the temperature remains constant. In adiabatic process, the system is thermally isolated and there is no change in heat temperature. The system returns to its initial stage in the cyclic process.
