Solution Summary
DNA is a macromolecule and consists of repeating units called as nucleotides. Each nucleotide is composed of - phosphate group, pentose sugar and nitrogenous bases. DNA molecule is a double stranded helical structure in which sugar and phosphate forms a back bone and Nitrogenous bases are connected with the help of hydrogen bonds.
The Sugar and phosphate of the two nucleotides are connected by a Phosphodiester bond.
DNA molecules stores information regarding the makeup of the next generation in the form of sequences of nitrogenous bases. These information are passed in the gametes which serve as the basis of the inheritance.
