The ABCs of Gene Cloning: Structures of Nucleic Acids [What is the chemical structure of a deoxyribonucleic acid (DNA) molecule? DNA is a polymer of deoxyribonucleotides. All nucleic acids consist of nucleotides as building units. A nucleotide has three components: sugar, base, and a phosphate group. (The combination of a sugar and a base is a nucleoside.) In the case of DNA, the nucleotide is known as deoxyribonucleotide, because the sugar in this case is deoxyribose.

Abstract

[What is the chemical structure of a deoxyribonucleic acid (DNA) molecule? DNA is a polymer of deoxyribonucleotides. All nucleic acids consist of nucleotides as building units. A nucleotide has three components: sugar, base, and a phosphate group. (The combination of a sugar and a base is a nucleoside.) In the case of DNA, the nucleotide is known as deoxyribonucleotide, because the sugar in this case is deoxyribose. The base is either a purine (adenine or guanine) or a pyrimidine (thymine or cytosine) (Figs. 2.1 and 2.3). Another type of nucleic acid is ribonucleic acid (RNA), a polymer of ribonucleotides also consisting of three components – a sugar, a base and a phosphate. The sugar in this case is a ribose, and that the base thymine is replaced by uracil (Sect. 2.6).]
