Question

Which of the following is a characteristic of double-stranded DNA?

A) 2 nanometers in width


B) 10 base pairs per turn


C) 0.34 nanometers per basepair


D) A and B


E) A, B and C

Answer 1

Double-stranded DNA is around 2 nanometers in width and has approximately 10 base pairs per turn in its helix.

Step-by-step explanation:

The characteristic of double-stranded DNA is represented by option D) A and B.

The width of double-stranded DNA is around 2 nanometers.

There are approximately 10 base pairs per turn of the helix.

These characteristics were discovered by Watson and Crick during their work on the structure of DNA, where they realized that the two strands of DNA form a helix and that there are specific base pairings between purines (A and G) and pyrimidines (T and C).
