Answer

(d) Inducer (e) Place where repressor binds to shut off operon (f) Substance that binds to promoter site to start transcription (d) Combines with repressor to keep operon “on” (c) Z, Y, A (a) May be located some distance from the operon and is not under control of the promoter (g) Protein that binds to operator preventing transcription of structural

Work Step by Step

The following are some of terms in lac operon and the corresponding description: Regulator gene- May be located some distance from the operon and is not under control of the promoter; Structural genes- Z, Y, A genes ; Lactose- Combines with repressor to keep operon “on” and Inducer; Operator- Place where repressor binds to shut off operon; RNA polymerase- Substance that binds to promoter site to start transcription; Repressor- Protein that binds to operator preventing transcription of structural
