Georgia Tech / Rob FeltProteins inside bacteria fluoresce in colors that reflect their differing genetic make-ups caused by rapid lab-generated mutations. The differences help researchers sort them into evolutionary trees.
-
Georgia Tech / Ryan RandallGeorgia Tech researcher Ryan Randall created an evolutionary tree by rapidly generating mutations of a fluorescing protein and laying out diverging pathways of their strains. Then she ran ancestral sequence reconstruction algorithms back down the tree to benchmark them. The ASRs proved highly accurate.
