The antiparallel arrangement within DNA molecules refers to
A)Each base bonding at the 1' position of the sugar
B)A purine always bonding to a pyrimidine
C)One helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction
D)An original parent DNA strand and one newly synthesized DNA strand comprising a new DNA molecule
E)None of the choices are correct

Question

Quizplus · Accepted Answer

The antiparallel arrangement within DNA molecules refers to one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction. This arrangement is important because it allows the two strands to properly base pair with each other and maintain the correct distance between the sugar-phosphate backbones. Options A and B are not specific to the antiparallel arrangement, while option D refers to semi-conservative replication. Option E is incorrect because option C is the correct choice.
