The diffraction patterns of DNA and statements related to this pattern are given below.
A. The radius, pitch, pitch angle, and the number of phosphate molecules per pitch of the DNA helix could be determined by using this diffraction pattern.
B. The diffraction pattern was described mathematically by Rosalind Franklin.
C. “X”-form distribution of the diffraction peaks is an indication of a helical structure.
D. The diffraction pattern of B-DNA has 15 base pairs per turn.
Which one of the following options represents all correct statements?
C and D
A and C
B only
A,B, C and D
The diffraction pattern was described mathematically by Watson and Crick. The diffraction pattern of B-DNA has 10 base pairs per turn. Therefore statements A and C are correct.Hence, the correct answer is option 2.
