BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).

Detailed explanation-2: -Nucleic acids are organic compounds that include DNA and RNA.

Detailed explanation-3: -The molecules that serve as the building blocks of DNA and RNA. Nucleotides consist of one nitrogenous base – adenine, cytosine, guanine, or thymine (uracil in RNA), a sugar (deoxyribose in DNA, ribose in RNA) and a phosphate group.

Detailed explanation-4: -Each strand of DNA is made of four types of molecules, also called bases, attached to a sugar-phosphate backbone. The four bases are adenine (A), guanine (G), cytosine (C), and thymine (T). The bases pair in a specific way across the two strands of the helix: adenine pairs with thymine, and cytosine pairs with guanine.
