The role of DNA (deoxyribonucleic acid) and proteins in a cell.
Introduction:
DNA is considered as a blueprint of a cell, as it plays an important role in long-term information storage. DNA is the genetic material of all living organisms and viruses except RNA viruses. Proteins are

Explanation of Solution
DNA: DNA is present in all living organisms and in some viruses. DNA is made up of the ribose sugar, a nitrogenous base, and a phosphate group. DNA plays an important role in a cell as it contains all the information required by a cell for its development and function. It acts as a genetic material and helps in the transfer of hereditary information.
Protein: Proteins are complex
DNA and protein playing important roles in a cell are considered as molecules of life. The proteins help in the maintenance of a normal structure and function in the body.
