Question

Antiparallel strands of a DNA molecules means that

Options

A.the phosphate group of two DNA strands, at their ends, share the the same position
B.the phophate groups at start of two DNA strands are opposite position (pole)
C.one strand turns clockwise
D.one strands turns anti-clockwise

Solution

J D Waston and F H C Crick (1953) showed that DNA has a double helical structure with two polynucleotide chains connected by hydrogen bond and running in opposite directions. The anti parallel strands of a DNA molecules means that the phosphate group at the start of two DNA strands are in opposite position (pole).
