Question

What are the general functions of nucleic acids in the body?

Answer 1

Hint: Nucleic acids are a kind of information (genetic) encoding molecules. It is present in DNA, RNA of cells of almost every organism irrespective of them being micro or macro organisms.

Complete answer:
Nucleic acid plays many crucial roles in conduction of several metabolic processes. Few of them are enlisted below:
Hereditary characters: Nucleic acids in the form of DNA and RNA play a vital role in carrying hereditary characters from one generation to another.
Protein synthesis: Nucleic acids in the form of RNA are specifically concerned with protein synthesis in the cytoplasm of cells thus satisfying protein needs of the body. Protein is a kind of nutrient that is chiefly required for building up of muscles.
Messenger: Nucleic acids in the form of mRNA functions as a messenger between DNA replication site and protein synthesis site.
Genetic storeroom: Nucleic acids in the form of DNA permanently store genetic information of an organism thus, maintaining his/her individuality. Besides, nucleic acids in the form of RNA temporarily store genetic information at the time of DNA replication, thus, contributing to efficient cell division processes.
Stability: Nucleic Acid in the form of rRNA contributes to stabilization of mRNA as they work as a catalyst in protein synthesising processes.
Genetic design: Nucleic acid in the form of DNA is concerned with genetically designing an organism. It carries information related to every single trait exhibited by the individual.

Note:
Nucleic acid.is chemical compound that needs not to be necessarily consumed through diet by the organism. It is simply a long chain of nucleotides thus is also called polymer of nucleotide or polymerase. It is specifically present in the nucleus of the cell.
