WebThe base pairs are almost perpendicular in B-DNA, whereas base pairs are titled in A-DNA. As a result, the depth of the deep grooves is increased and that of shallow grooves is reduced. C-DNA: The C-form of DNA is observed when humidity of DNA fibre is below 66%. This form of DNA has pitch of 3.1nm and 9.3 base pairs per turn of the helix. WebCalculate the number of helical turns if the DNA were in the B form, given that B‑form DNA contains 10.5 base pairs per helical turn. Suppose that a length of double‑stranded DNA is 25202520 base pairs long. Calculate the number of helical turns if the DNA were in the B form, given that B‑form DNA contains 10.5 base pairs per helical turn.
