Biotechnology : Principles And Processes

Question

Width of the DNA molecule is

15 A^o

20 A^o

25 A^o

34 A^o

Solution

20 A^o

The 3-D structure of DNA is represented by a double helix, in which each turn has a diameter of 34 Å and contains 10 base pairs at a distance of 3.4 Å. The width of DNA molecule is 20 Å.
