Remember: The backbone of the DNA molecule consists of the deoxyriboses linked by phosphodiester bridges (i.e., the 3'-OH group of the sugar of one is linked to the 5'-OH of the next sugar by a phosphate). The variable part of the DNA is the sequence of the bases, and the precise sequence of the pur ...
