Question

Why are DNA strands considered as antiparallel?

Answer 1

Antiparallel (biochemistry) In biochemistry, two biopolymers are antiparallel if they run parallel to each other but with opposite alignments. An example is the two complementary strands of a DNA double helix, which run in opposite directions alongside each other.

Answer 2

because replication occur in two different way at two strands. for example leading strands in one way and lagging strand in another way. Thank you.
