Question 1

1.

What is a regulatory gene?

a gene that codes for proteins invloved with DNA regulation 

a gene that codes for proteins invloved with translation 

a gene that codes for proteins invloved with DNA replication

a gene that codes for proteins invloved with carbohydrate regulation

Question 2

2.

What is a repressor protein?

protein that binds to the operator affecting the rate of translation

protein that binds to the operator affecting the rate of transcription

protein that binds to the operator inhibiting transcription

protein that binds to the operator increasing the rate of transcription

Question 3

3.

What is a transcription factor

carbohydrates that that initiate and regulate the transcription of genes

proteins that that initiate and regulate the transcription of genes

lipds that that initiate and regulate the transcription of genes

proteins that that initiate and regulate the translation of genes

Question 4

4.

What is a structural gene?

Structural genes code for the synthesis of specific amino acid sequence that are invloved in gene regulation

Structural genes code for the synthesis of specific amino acid sequence that are not invloved in gene regulation

Question 5

5.

What is the promotor region?

A promoter is a region of DNA upstream of a gene where relevant proteins (such as RNA polymerase and transcription factors) bind to initiate tranlation of that gene

A promoter is a region of DNA upstream of a gene where relevant proteins (such as DNA polymerase and transcription factors) bind to initiate transcription of that gene

A promoter is a region of DNA upstream of a gene where relevant proteins (such as RNA polymerase and transcription factors) bind to initiate transcription of that gene

A promoter is a region of DNA upstream of a gene where relevant proteins (such as RNA polymerase and transcription factors) bind to inhibit transcription of that gene
