Solution

The correct option is C 36o
  • The DNA in humans is a double helix. Pitch is the number of base pairs in one complete turn of the helix.
  • There are 10 base pairs in 1 complete turn and the distance between 2 bases is 0.34nm.
  • The deflection between two successive base pairs has a pitch angle of 36o.
    Thus the correct answer is option C.
