DNA Structure Guided Investigation, Years 9–10
A five-step investigation in which students identify complementary base pairing on the ladder view, compare hydrogen bonds in C–G and A–T pairs, reveal 5′/3′ strand directions, locate a gene segment and apply a supplied sequence to inspect its complementary strand. The full interactive is available to licensed Education Universe users.
