1. DNA=Deoxyribonucleic Acid.

2. The organic molecules that serve as monomer units for forming the nucleic acid polymers DNA and RNA both of which are essential bio molecules within all life forms on earth is called nucleotide.

3. DNA is made up of molecules called nucleotide. Each nucleotides contains a phosphates group, sugar group and a nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).

4. A threadlike structure of nucleic acid and protons found in the nucleus of most living cells, carrying genetic information in the form of genes is called chromosome.

4. The complete set of genes or genetic material present in a cell or organism is called genome.
