Based on the current understanding of this operon, which hypothesis would be useful for James to test? Addition of allolactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose. Removal of the RNA polymerase molecule should increase the amount of bacterial growth on the plate. Decreasing the amount of allolactose in the bacterial growth media should increase the rate of bacterial growth. Increasing the rate at which RNA polymerase acts will inhibit bacterial growth

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
