Each strand consists of alternating molecules of deoxyribose and phosphate groups. Each step is made up of a double ring purine base and a single ring pyramiding base. The purine and pyrimidine bases and a single ring pyramiding base. The purine and pyrimidine bases are connected to deoxyribose sugar molecules. The two strands are interwined in a clockwise direction, i. The strand completes a turn each 34A. The DNA molecule is a polymer consisting of several thousand pairs of nucleotide monomers.

Each nucleotide consists of the pentose sugar deoxyribose, a phosphate group and a nitrogenous base which may be either a purine or a pyrimidine.

Deoxyribose and a nitrogenous base together form a nucleoside. A nucleoside and a phosphate together form a nucleotide. Deoxyribose is a pentose sugar with five carbon atoms. Four of the five carbon atoms plus a single atom of oxygen form a five membered ring. The fifth carbon atom is outside the ring and forms a part of a —CH2 group.
