Genes That are Continually Being Expressed in Most Cells Are

Question

Genes that are continually being expressed in most cells are referred to as
A) inducible genes.
B) repressible genes.
C) constitutive genes.
D) tRNA genes.
E) mRNA genes.

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.
