Explanation:
Detailed explanation-1: -A nucleotide is the basic building block of nucleic acids (RNA and DNA).
Detailed explanation-2: -The Four Macromolecules. All life is composed mainly of the four macromolecule building blocks: carbohydrates, lipids, proteins, and nucleic acids. The interactions of different polymers of these basic molecule types make up the majority of life’s structure and function.
Detailed explanation-3: -DNA is a molecule made up of four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). For the two strands of DNA to zip together, A pairs with T, and C pairs with G. Each pair comprises a rung in the spiral DNA ladder.
