Answer:
Poly-nucleotide.
Explanation:
Nucleotide are basic building blocks of DNA molecules which is composed of a sugar, a phosphate and a base. While many nucleotide strung together they a poly-nucleotide molecules.
When more nucleotide composed together by a covalently bounded in a chain they form the poly-nucleotide molecule.
Example of poly-nucleotide molecules are Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) with different in biological function. Poly-nucleotides are present in all organisms naturally. RNA consists a poly-nucleotide and DNA consist a pair of poly-nucleotides.
