When double-stranded DNA replicates, the newly made strand is related to its template strand because the two strands have complementary sequences and are antiparallel to each other. This means that they run in opposite directions, with one strand running 5' to 3' and the other running 3' to 5'. The complementary base pairing between the nucleotides on the two strands allows for accurate replication of the DNA sequence.
