Arаbinоse is а cаrbоn sоurce for E. Coli. If arabinose is not present in the bacteria’s environment, they will not express the enzymes (AraA and AraB) that are required to break it down into glucose. The presence of arabinose leads to the expression of the AraA and AraB enzymes that are required for arabinose breakdown. The table below shows this wild-type response. The table also shows the altered response of two mutants (M1 and M2; M1+/M2+ indicate the wild-type allele). “on” and "off" in the table indicate enzyme activity or inactivity. a. [1] What could account for M1-? b. [2] What could account for M2-? c. [3] How would the presence arabinose affect the regulatory protein?
