Melanie gets poetic in Episode 69. Roses are red, violets are blue. If a promoter is blocked this may be untrue. Make sure to appropriately distinguish between genes and alleles (1:59). Gene expression occurs at many levels, all of which are essential in producing an organism’s phenotype (3:03). The episode concludes with a recap of the Lac Operon - everyone’s favorite bacterial gene expression example (6:17).
