Solution
The correct option is C Phosphodiester bond
The DNA molecule, is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends. One end is called as 5' (5 prime), the other is called as 3' (3 prime). The names come from the notation for the two sugar carbon atoms which participate in the phosphodiester bonds. The different strands in the helix run in opposite (anti-parallel) directions. At each end of the double helix, one strand is 5' and the other is 3'. Therefore, the correct answer is option C.
