DNA Nucleotide Love Card

Express your love with DNA!  The DNA code has four letters (called “nucleotides”) in its alphabet: A, T, C, and G.  A and T are always paired, while G and C are always paired, which have been interpreted as epic love connections.  

The chemical structures of each of these pairings are shown on two versions of the card — A-T on a red card and G-C on a lime green card. Choose your pair from the drop-down menu.

This card is popular with biologists and chemists alike.  Perfect for Valentine's Day, your Anniversary, or whenever.

Greeting:  I need you like A needs T (or G needs C)
Inside:  blank
