An inducible gene gets expressed in the presence of a an inducer which can control the expression of one or more genes called to be structural genes those are involved in the metabolism or synthesis of target or inducer itself as substance. so see the lactose induces the expression of the lac genes which plays role lactose metabolism.
For example a certain antibiotic which induce the expression of a gene that leads to resistance to that antibiotic. presence of Inducer is common in metabolic pathways that itself catabolism pathway and acts as he substrate for the pathway.
Repressible genes turns off the expression of structural gene involved in the metabolism of that substance a co-repressor in the environment. For example e.g., Tryptophan represses the expression of the trp genes. biosynthesis of a substance example of repressible. so thi can not be beneficial.
so by above two reaction we can see the inducible pathway is quite beneficial.

The tryptophan operon is negatively repressible and tryptophan acts as a cofactor. What should happen in the absence of tryptophan? the genes in the operon should be enhanced The genes in the operon should be transcribed the genes in the operon should not be transcribed The genes in the operon should be silenced

Question 1 (1 point) The sunshine operon regulates a series of genes that help one respond favorably to warm weather and sunlight. The regulator of this operon is usually bound to DNA, but becomes inactive (i.e., it falls off the DNA) when a small molecule binds to it that inactivates its DNA binding properties. What is the term for the type of regulatory control of this operon? Repressible Inducible Constitutive Catabolic Photophobic Question 2 (1 point)

Answer please I will give thumbs up
In a negatively inducible operon, the regulatory protein is An inhibitor that is activated when a cofactor is present. An inhibitor that is repressed when a cofactor is present. An activator that is activated when a cofactor is present. An activator that is inhibited when a cofactor is present.
