EXPLANATION:

There are 2 types of nucleic acids: DNA(deoxyribonucleic acid) and RNA(ribonucleic acid).

Living organisms have their genetic material in their DNA. Viruses use RNA as their genetic material but are usually called non-living things( because they can't reproduce without help from a host).

The function of nucleic acids has a progression from DNA to RNA to proteins. This is called the central dogma of molecular biology.

Nucleic acids are formed by a linkage of polynucleotide chains with phosphodiester bonds. These polynucleotide chains are formed from monomers called NUCLEOTIDES.

A nucleotide is made up of 3 parts:

i) a nitrogenous base

ii) a five-carbon sugar

iii) at least one phosphate group.
