Antiparallel strands of a DNA molecule m...

Antiparallel strands of a DNA molecule means that `:`

A

the phosphate group of two DNA strands, at their ends, share the same position

B

the phosphate group at the start of two DNA strands are in opposite position (pole)

C

one strands runs clockwise

D

one strand runs anti-clockwise

Text Solution

Verified by Experts

The correct Answer is:
B
J D Watson and F H C Crick (1953) showed that DNA has a double helical structure with two polynucleotide chains connected by hydrogen bonds and running in opposite directions (antiparallel). The antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole).
