Question

what direction do the dna strands run? antiparallel perpendicular parallel

Explanation:

DNA strands are known to run in an antiparallel direction. This means the two strands run in opposite directions (one in 5' to 3' and the other in 3' to 5'), which is a fundamental property of the DNA double helix structure. Perpendicular would mean they are at right angles (not the case for DNA strands), and parallel would mean they run in the same direction (which DNA strands do not).

Answer:

Antiparallel
