Question

The pitch of the DNA helix is 3.4 nm.

• A. True
• B. False

Answer 1

The correct option is A True

The double helix DNA turns after every 10 base pairs at a distance of 3.4 nm. This distance is called pitch. The distance between two base pairs is 0.34 nm. Hence, the statement given in the question is correct.

So, the correct answer is 'True'.
