Tap each word to check what it stands for.

When to use it

Use it when completing a complementary DNA strand to pair each base with its correct partner.

Example

For the strand 5'-ATCG-3', the complementary strand is 3'-TAGC-5', using Apple Tree (A pairs T) and Car Garage (C pairs G) for each base.

Common mistake

Applying RNA pairing rules to DNA. In DNA, adenine pairs with thymine; in RNA, adenine pairs with uracil instead.
