The free virtual lab comes from Brian White and Ethan Bolker of the University of Massachusetts, Boston. Students begin by setting up plant crosses and gene mutations to decipher the inheritance of color in fictional flowers. They then move to the protein level, tinkering with amino acid sequences to see how changes alter a protein's shape and the flower color it produces. The final exercises let users determine the consequences of manipulating DNA.
