DNA replication can occur only in one direction (but remember, these two strands are antiparallel). Each slide has information on a step in DNA synthesis process. The model for DNA replication suggests that the two strands of the double helix separate during replication, and each strand serves as a template from which the new complementary strand is copied. A thorough lesson demonstration models DNA replication with a 3-D animation. The DNA polymerase attaches to the unwound strands of DNA, but this enzyme can only extend the primer from 5′ to 3′.
