WebCorrect option is A) The double helix DNA turns after every 10 base pairs at a distance of 3.4 nm. This distance is called pitch. The distance between two base pairs is 0.34 nm. Hence, the statement given in the question is correct. So, the correct answer is 'True'. WebB-DNA is een rechtsdraaiende dubbele helix met een radius van 10 Å, waarbij tien basenparen nodig zijn voor een volledige draai om de hoofdas. Deze draaifrequentie (de zogenaamde helical pitch) hangt voornamelijk af van de stacking-interacties tussen de basenparen. DNA is redelijk vervormbaar kan verschillende conformaties aannemen.
