Question

A(n) ______ is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.

The _________ is/are arranged sequentially after the promoter

A(n) ______ is a specific nucleotide sequence in DNA that binds RNA polymerase, positioning it to start transcribing RNA at the appropriate place.

A(n) _______ codes for a protein, such as a repressor, that controls the transcription of another gene or group of genes.

Regulatory proteins bind to the ________ to control expression of the operon.

A(n) ______ is a protein that inhibits gene transcription. In prokaryotes, this protein binds to the DNA in or near the promoter.

A(n) ______ is a specific small molecule that binds to a bacterial regulatory protein and changes its shape so that it cannot bind to an operator, thus switching an operon on.

Answer 1

A(n) operon is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.

The genes of an operon is/are arranged sequentially after the promoter.

A(n) promoter is a specific nucleotide sequence in DNA that binds RNA polymerase, positioning it to start transcribing RNA at the appropriate place.

A(n) regulatory gene codes for a protein, such as a repressor, that controls the transcription of another gene or group of genes.

Regulatory proteins often bind to the operator to control expression of the operon.

A(n) repressor is a protein that inhibits gene transcription. In bacteria, this protein binds to the DNA in or near the promoter.

A(n) inducer is a specific small molecule that binds to a bacterial repressor protein and changes its shape so that it cannot bind to an operator, thus switching an operon on.
