Suppose an operon has the following characteristics: (1) The operon codes for structural proteins that convert compound Qto compound B. (2) The operon is controlied by a constitutively expressed regulatory gene called reg. (3) In wild-type individuals, the operon is transcribed in the absence of compound B but not in the presence of compound B. (4) in reg mutants, the operon is constitutively transcribed. Is this operon inducible or repressible? Why? O It is inducible because wild-type transcription does not occur in the presence of compound B. O t is inducible because the operator in reg mutants can still bind to compound B O It cannot be determined because the number of structural genes is unknown. O t is repressible because reg transcription only occurs in the presence of compound B O t is repressible because wild-type transcription is repressed in the presence of compound B Which of the following is the triangle proportionality theorem Manganese metal can be prepared by the thermite process: 4Al(s) . 3MnO2(s). -->. 3Mn(l). 2Al2O3(s) molar masses, in g/mol: 26.98. 86.94 54.94 101.96 If 203 g of Al and 472 g of MnO2 are mixed, which is the limiting reactant? what mechanical layer sits on top of the Asthenosphere Find the sample size required to estimate the percentage of college students who use student loans to help fund their tuition.
