Proteins and Nucleic acids are two different macromolecules that are not similar in structure and function.Proteins are a polymer of amino acids. Nucleic acids,on the other hand is a polymer of nucleotides composed of a pentose sugar , a nitrogenous base and a phosphate group.proteins play many important roles in human body including maintenance of structure of cells,regulating mitosis and meiosis,and also controlling body’s metabolism.Main role of nuclec acids(DNA & RNA) is to store the genetic information and pass on to the next generation of each organisms.Even though they are different in structure and function they are closely related to each other.They both interact with each other to perform their biological functions.
