Biochemical structure of dna
WebOct 24, 2024 · Deoxyribonucleic acid (DNA) is a double helix composed of two strands of four types of nucleotides.[1] Each nucleotide consists of the sugar deoxyribose, a nitrogenous base, and a phosphate group.[2] These four nucleotides include adenine (A), thymine (T), cytosine (C), and guanine (G). They always pair together with the same … WebNow let’s consider the structure of the two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group , and a nitrogenous base ( Figure 9.3 ).

Deoxyribose sugar in DNA is less reactive because of the carbon- hydrogen bonds.
WebThe structure of DNA, as represented in Watson and Crick's model, is a double-stranded, antiparallel, right-handed helix. The sugar-phosphate backbones of the DNA strands make up the outside of the helix, while the nitrogenous bases are found on the inside and form hydrogen-bonded pairs that hold the DNA strands together.
