Question

The antiparallel arrangement within DNA molecules refers to Select one:

Answer 1

Answer:

c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.

Explanation:

A DNA molecule has two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction allowing for the base pairs to complement one another, making it a more stable structure. When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.

I annexed an image of the DNA structure.
