DNA is a double helix, and it is made out of polynucleotides
Work Step by Step
DNA is made out of nucleotides, which are made out of a pentose, phosphate, and a nitrogenous base. Each strand is connected from the 5' on the phosphate and 3' on the pentose. The double helix in DNA is created from the hydrogen bonds between the nitrogenous bases from the two strands.
