RNA is a copy of DNA that is used to make proteins. We usually compare all eukaryotic cells as a group to all prokaryotic cells.
The answer is negative inducible and positive repressible.
This is because, since the gene is constitutive, it is always transcribed
unless repressed. It is also structural because it codes for enzymes or proteins
that are non-regulatory. The fact that transcription factors cannot bind to the
promoter means it cannot be transcribed (hence also repressed by the mutation).
