Detailed explanation-1: -DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide, DNA or RNA. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar, and a phosphate group.

Detailed explanation-2: -Organic compounds essential to human functioning include carbohydrates, lipids, proteins, and nucleotides. These compounds are said to be organic because they contain both carbon and hydrogen.

Detailed explanation-3: -DNA is made of nucleotides consisting of a sugar, a phosphate group, and a carbon base. DNA is made of a single polynucleotide chain, which winds into a double helix. DNA is how inherited characteristics are passed from one generation to the next.

Detailed explanation-4: -A nucleotide is one of a class of organic compounds composed of three subunits: one or more phosphate groups. a pentose sugar: either deoxyribose or ribose. a nitrogen-containing base: adenine, cytosine, guanine, thymine, or uracil.
