Detailed explanation-1: -Nucleotides that compose DNA are called deoxyribonucleotides.
Detailed explanation-2: -Nucleic acids are macromolecules, which means they are molecules composed of many smaller molecular units. Thes units are called nucleotides, and they are chemically linked to one another in a chain. In DNA, the nucleotides are referred to in shorthand as A, C, T, and G. In RNA, the nucleotides are A, C, U, and G.
Detailed explanation-3: -Deoxyribonucleic acid (DNA) is a long, double-stranded, helical molecule composed of building blocks called deoxyribonucleotides.
Detailed explanation-4: -1. A molecule of DNA consists of two strands that form a double helix structure. DNA is a macromolecule consisting of two strands that twist around a common axis in a shape called a double helix.
Detailed explanation-5: -Molecular Cell Biology DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.
