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 is one of the three components of nucleotides, the building blocks of DNA. Each nucleotide consists of a phosphate group, a nitrogenous base-adenine (A), thymine (T), cytosine (C), or guanine (G)-and deoxyribose.
Detailed explanation-3: -These chemical bonds act like rungs in a ladder and help hold the two strands of DNA together. There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).
Detailed explanation-4: -Each nucleotide, in turn, is made up of a nitrogenous base, a pentose sugar, and a phosphate.
Detailed explanation-5: -Deoxyribose+phosphate group+cytosine is a nucleotide found in DNA. (option 4)
