Concept explainers
(a)
To calculate: The total bend produced in a DNA if the center base pairs of two successive (dA)5 tracts located 10 base pairs apart.
Concept introduction:
DNA is a flexible molecule and rotation is possible around different type of bonds in the backbone which is made up of sugar and phosphate groups. Thernall fluctuation in the backbone of DNA could produce bending, unpairing of strands and stretching.
(b)
To calculate: The total bend produced in a DNA if the center base pairs of two successive (dA)5 tracts are located 15 base pairs apart is to be determined.
