WebBase pairing The nucleotides are identical except for the base, which can be an adenine, thymine, guanine or cytosine. There are chemical cross-links between the two strands in DNA, formed by... WebDNA polymerases can only make DNA in the 5' to 3' direction, and this poses a problem during replication. A DNA double helix is always anti-parallel; in other words, one strand runs in the 5' to 3' direction, while the other runs in the 3' to 5' direction.
