Answer: DNA is antiparallel because Its double strands run in opposite directions.
Explanation: The antiparallel nature of DNA strands means that as one strand runs in 5'->3' direction, the other strand runs in 3'->5' direction.

This means that anywhere thymine base is found in one strand, adenine is present in the other strand and anywhere guanine occurs in one strand, cytosine occurs in the other strand.
