Question

Quizplus · Accepted Answer

Constitutive genes are those that are continually being expressed in most cells without regulation. Inducible genes are only expressed when a specific signal or inducer is present. Repressible genes are usually active but can be turned off in the presence of a specific repressor molecule. tRNA genes code for tRNA molecules, which are involved in translation, while mRNA genes do not exist as they are a product of transcription rather than a separate gene.
