Andrei [34K]

Answer:Inducible;inducer

Explanation:

Induction is the phenomenon of increased synthesis of protein or and enzyme in response to certain signal. Such enzymes are called inducible and the signals are called inducer. Induction is turning ''on''the switch of a gene.

When M is present in the medium, M binds the repressor protein. The repressor-M complex is inactive which does not bind to the operator region of LM. Now RNAP can transcribe the structural genes of LM.

M switches the gene ''on''. Hence M is an inducer of LM. LM is an inducible operon
