Hint: Biopolymers, or big macromolecules, such as nucleic acids are required for all known forms of life. They are made up of nucleotides, which are three-component monomers consisting of a 5-carbon sugar, a phosphate group, and a nitrogenous base.

Complete answer:
Nucleic acids are naturally occurring chemical substances that make up the genetic material and act as the major information-carrying molecules in cells. Nucleic acids are abundant in all living things, where they produce, encode, and store information for every living cell in every life form on the planet. They then convey and express that information to the cell's inner activities and, ultimately, to the future generation of each living thing, both inside and outside the nucleus. The nucleic acid sequence, which provides the 'ladder-step' ordering of nucleotides within the molecules of RNA and DNA, contains and conveys the encoded information. They're particularly critical for controlling protein synthesis.
Nucleic acids make up a cell's hereditary material, allowing living creatures to carry genetic information from one generation to the next. Nucleic acids are divided into two categories: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) (RNA). Despite the fact that DNA and RNA have extremely similar chemical compositions, they play quite diverse biological activities.

Note:
Nucleic acid is a component of all living things and serves as the foundation for DNA and RNA. It's found in every cell, as well as several viruses. Nucleic acids have a wide range of tasks, including cell formation, genetic information storage and processing, protein synthesis, and energy cell generation.
Despite the fact that their roles differ, DNA and RNA have very similar structures, with just a few fundamental variations in their molecular make-up distinguishing them.
