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.
