Related Post Which Statement(S) About Inducible Operons Is/Are Correct? :
This process is a tightly coordinated process which allows a cell to respond to its changing environment. While the lac operon can be activated by a chemical (allolactose), the tryptophan (trp) operon is inhibited by a chemical (tryptophan).this operon contains five structural genes: There is a adenosine at the 3� terminus. The first operon codes for various products, including a special t7 rna polymerase which can bind to and transcribe the second operon.
Which statement(s) about repressible operons is/are correct?
Some operons are considered inducible while others are repressible. D) choice (a) is correct. R+ is dominant in trans. Some operons are considered inducible while others are repressible. If the statement is false, either correct the statement or give a counterexample. It would be wasteful to produce enzymes when no lactose is available or if a preferable energy source such as glucose were available.

As long as the product of the pathway, like tryptophan, continues to be required by the cell, a repressible operon will continue to be expressed. Glucose is the preferred carbon source for many bacteria, and the operons for metabolism of other sugars, such as lactose and arabinose, are less active when glucose is available (even in the presence of inducer). Catabolite repression involves the accumulation of cyclic amp.
