16. During early life many infants receive milk from the mother. One of the major components of milk is lactose. a) Consider the Lac operon in E. coli, and state what the expression of Lac Y would be in I) E. coli WT (wild type, everything is functional) and II) E. coli whose lacl gene has been delet- ed, when each of the 2 strains are growing in culture flasks that contain high glucose and high lactose. Hint: choose among 'high expression; low expression; no expression'for I) and II). 1) II) b) In the graph below, draw the expression of LacY over time in strains I and II, when each of the 2 strains are growing in culture flasks that contain high glucose and high lactose, as shown in part a). Hint: you can draw the curves on a piece of paper and copy and paste a picture of it, if it is difficult to draw the graph directly here. If you do so and you have a Mac, make sure to convert your exam into PDF by doing "Print > Save as PDF"; do not “Export as PDF". time (min) Make sure to label which curve refers to strain I and which one refers to strain II. LacY expression
