Imagine you are introducing the Lac operon and the Trp operon to students who have never learned about it before. Complete the table to compare the similarities and differences between the two operons.

(I hope you can understand this)

Type of operon:                                   Trp

                                             It’s a repressible operon        

                                                            Lac

                                            It’s an inducible operon.

Environment:    

                                                             Trp

              It’s deactivated when tryptophan is present in the environment.

                                                            Lac

              It’s activated when lactose is present in the environment.

Repressor protein:

                                                      Trp

                                       It’s activated by tryptophan.

                                                              Lac

                                           It’s inactivated by lactose.

Transcription:

                                                               Trp

                   Tryptophan binds to the repressor protein, activating it.

                                                               Lac

            Lactose binds to the repressor protein, deactivating it.

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.
