It Had to be U - Uracil U

A song about transcription to remember that uracil in mRNA replaces thymine in DNA. Singalong to the classic "It Had to Be You" (music not included for copyright reasons). Some students might be reluctant to sing; but all will join in the actions as you singalong- making the letters A;C;G;T and U using their arms (YMCA style!).
