Double-stranded DNA consists of two antiparallel strands, meaning that one strand is oriented in the 5' to 3' direction, while the other is oriented in the 3' to 5' direction.

a. true

b. false

The answer is a) True.

Explanation:

The structure of DNA gives information about why it's the genetic molecule. Being antiparallel means, as the question says, that one goes from 5' to 3' and the other one from 3' to 5'. Also there's a correspondency on the bases, this means that when it's separated and replicated, the result will be the same information but in two separate and complete DNA.
