Ans.D. Inserting or knocking out a gene.
By inserting or knocking out genes, the importance of specific genes on the genesis of disease and its effects on complex biological pathways in various tissues can be observed.
An inducible gene is one whose expression increases in response to an inducer or activator, a specific positive regulatory signal.
The expression of some genes is constitutive, meaning that they are expressed at a reasonably constant rate and not known to be subject to regulation.
These are often referred to as housekeeping genes.
