Question

component of DNA molecules

Answer 1

A nucleotide is each composed of a phosphate group, a deoxyribose sugar molecule which is pentose sugar (5 carbon), and any one of the four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.

Answer 2

hello,

• DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
