Detailed explanation-1: -Answer and Explanation: DNA is made up of three key components. Every DNA nucleotide is composed of a sugar molecule called deoxyribose, a phosphate group, and a nitrogenous base. Differences in the structure of the nitrogenous base are what distinguish the nucleotides.
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: -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: -The adenosine phosphate nucleotides have ribose as the five carbon sugar and adenine as the nitrogenous base. These nucleotides differ in the number of inorganic phosphate groups phosphorylated to the ribose, which can vary from one to three.
Detailed explanation-5: -With all three joined, a nucleotide is also termed a “nucleoside monophosphate", “nucleoside diphosphate” or “nucleoside triphosphate", depending on how many phosphates make up the phosphate group.
