उत्तर
A bacterial gene that is perpetually active is said to be constitutive.
Explanation:
Constitutive genes are expressed continuously at a constant rate because their protein products are always needed for basic cellular functions. Often called “housekeeping genes,” they are not regulated by environmental signals, unlike inducible genes (which turn on only when needed) or repressible genes (which turn off when their product is abundant).
