Detailed explanation-1: -DNA consists of two nucleotide chains that are bonded to together by weak hydrogen bonds between complementary base pairs. The double strands are wrapped to form a double helix.

Detailed explanation-2: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

Detailed explanation-3: -Definition. Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder-a shape known as a double helix.

Detailed explanation-4: -DNA is a polymer of the four nucleotides A, C, G, and T, which are joined through a backbone of alternating phosphate and deoxyribose sugar residues. These nitrogen-containing bases occur in complementary pairs as determined by their ability to form hydrogen bonds between them.

Detailed explanation-5: -Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
