What is the primary function of nucleic acid?

Hint: We can define Nucleic acids as long-chain polymeric particles, the monomer (the repeating unit) is known as the nucleotides and subsequently in some cases nucleic acids are alluded to as polynucleotides.

Complete answer:
We have to know that Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two significant sorts of nucleic acids. DNA and RNA are known for the legacy and transmission of particular characteristics from one age to the next. There are unmistakably two kinds of nucleic acids known to us.
Artificial DNA is made out of a pentose sugar, phosphoric acid and some cyclic bases containing nitrogen. The sugar moiety present in DNA atoms is β-D-2-deoxyribose. The cyclic bases that have nitrogen in them are adenine (A), guanine (G), cytosine(C) and thymine (T). These bases and their course of action in the particles of DNA assume a significant part in the capacity of data starting with one age then onto the next one. DNA has a twofold strand helical design in which the strands are reciprocal to one another.
The RNA molecule is additionally made out of phosphoric acid, a pentose sugar and some cyclic bases containing nitrogen. RNA has β-D-ribose in it as the sugar moiety. The heterocyclic bases present in RNA are adenine (A), guanine (G), cytosine(C) and uracil (U). In RNA the fourth base is unique in relation to that of DNA. The RNA for the most part comprises a solitary strand which here and there folds back; that outcomes in a twofold helix structure. There are three kinds of RNA particles, each having a particular capacity:
Messenger RNA (m-RNA)
Ribosomal RNA (r-RNA)
Transfer RNA (t-RNA)
The major functions of nucleic acids include:
Nucleic acids are liable for the transmission of intrinsic characters from parent to posterity.
They are required for the combination of proteins in our body.
DNA fingerprinting is a technique utilized by legal specialists to decide paternity. It is likewise utilized for recognizing criminals. It has additionally assumed a significant part in investigations in regards to organic development and hereditary qualities.

Note:
In simple words, we can define nucleic acids as large biochemical molecules which store and shift the genetic data in the cell. They utilize the genetic data which is stored to route for the combination of new proteins in the cell.
