👉 Nucleotides are the building blocks of DNA and RNA, which are the primary components of life. They consist of a sugar molecule called deoxyribonucleic acid (DNA) and a nitrogen-containing group called ribonucleotide (RNA). The nucleotide sequence is composed of four types of bases: adenine (A), thymine (T), guanine (G), and cytosine (C). Each type of base has an opposite complementary base, such as A
