Are Constitutive Genes Regulated?

Constitutive genes are always being expressed (usually at a basal/regular level) but regulated genes are only expressed under certain necessary conditions in order to save cellular energy. ... This is an advantage because it means the bacteria only needs one operon in order to regulated multiple genes.

What genes are regulated?

1: Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, as well as during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins.

Are constitutively expressed genes unregulated?

Just as the cellular requirements for different proteins vary, the mechanisms by which their respective genes are regulated also vary. ... Constant, seemingly unregulated expression of a gene is called constitutive gene expression.
