Solution
The correct option is D 5, 3 locations
In the nucleic acids, the phosphate ions are bonded with sugar at 5, 3 locations. The sugars and phosphates in nucleic acids are connected to each other in an alternating chain (sugar-phosphate backbone) through phosphatediesters linkages. The carbons to which the phosphate groups attach are the 3'-end and the 5'-end carbons of the sugar. This gives nucleic acids directionality, and the ends of nucleic acid molecules are referred to as 5'-end and 3'-end.
