Explanation:
Detailed explanation-1: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
Detailed explanation-2: -Deoxyribose Nucleotide As mentioned, deoxyribose is the sugar in the sugar-phosphate backbone of DNA. DNA is a polymer made up of a series of nucleotides. One nucleotide consists of a purine or pyrimidine nucleobase, one deoxyribose, and one phosphate group.
Detailed explanation-3: -DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T).
