Question

Define the four categories of gene regulation by placing the correct term in each sentence. terms can be used more than once.

1. in negative inducible control, the transcription factor is a(n)_____ binding of the signal molecule to the transcription factor causes transcription to
2. in negative repressible control, the transcription factor is a(n) ______ binding of the signal molecule to the transcription factor causes transcription to
3. in positive inducible control, the transcription factor is a(n) ____binding of the signal molecule to the transcription factor causes transcription to
4. in positive repressible control, the transcription factor is a(n) _____ binding of the signal molecule to the transcription factor causes transcription to ____

Answer 1

There are four categories of gene regulation: negative inducible control, negative repressible control, positive inducible control, and positive repressible control.

Step-by-step explanation:

In gene regulation, cells control the expression of genes through various mechanisms. There are four categories of gene regulation: negative inducible control, negative repressible control, positive inducible control, and positive repressible control.

In negative inducible control, the transcription factor is a repressor. Binding of the signal molecule to the transcription factor causes transcription to be turned off.

In negative repressible control, the transcription factor is a repressor. Binding of the signal molecule to the transcription factor causes transcription to be turned on.

In positive inducible control, the transcription factor is an activator. Binding of the signal molecule to the transcription factor causes transcription to be turned on.

In positive repressible control, the transcription factor is an activator. Binding of the signal molecule to the transcription factor causes transcription to be turned off.
