The reason why two strands of DNA molecules can be separated more easily at a pH more than 11. Concept introduction: A deoxyribonucleic acid (DNA) molecule is made up of a helical strand that is composed of complementary nucleotide base pairs. The typical structure of a DNA molecule consists of two strands that are twisted around each other like a twisted ladder. The rails of the ladder are made up of sugar and phosphate molecules in an alternative way. The steps are made up of two bases that are linked together with either two or three weak hydrogen bonds.
