In gene regulation and control, induction can be defined as the:
a. mechanism of genetic control in which genes are induced only when the substrate to be degraded by enzymatic action is present.
b. uptake of free DNA from the environment and recombination with the recipient's homologous DNA.
c. mechanism of genetic control in which genes are not transcribed and therefore are not expressed in the presence of those target products in sufficient supply.
d. change of the bacterial genotypes through the exchange of DNA from one cell to another.
A
To avoid waste and overproduction of enzymes in the cell, some genes are turned on only by the presence of the substrate of that gene expression.
