BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Deoxyribose is the five-carbon sugar molecule that helps form the phosphate backbone of DNA molecules. DNA, or deoxyribonucleic acid is a polymer formed of many nucleic acids. Each nucleic acid is composed of a deoxyribose molecule bound to both a phosphate group and either a purine or a pyrimidine.

Detailed explanation-2: -The model of the double-helix structure of DNA was proposed by Watson and Crick. The DNA molecule is a polymer of nucleotides. Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group.

Detailed explanation-3: -deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases.

Detailed explanation-4: -Phosphodiesters in DNA and RNA The phosphodiester backbone of DNA and RNA consists of pairs of deoxyribose or ribose sugars linked by phosphates at the respective 3’ and 5’ positions. The backbone is negatively charged and hydrophilic, which allows strong interactions with water.

Detailed explanation-5: -The monomer units of DNA are nucleotides, and the polymer is known as a “polynucleotide.” Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
