Question

What is the typical distance between two base pairs in nm?

• A. 0.34 nm
• B. 0.32 nm
• C. 0.33 nm
• D. 0.35 nm

Answer 1

Answer:

A. 0.34 nm

The double stranded helical structure of the DNA, takes a turn after every 10 base pairs which is noted to be as 3.4 nm. This is called as a pitch (distance). 0.34 nm is considered to be the distance between 2 base pairs.
