AGC box is a lecture and an article as part of the gene transcription series.

You are free to take this quiz based on the AGC box at any time.



Suggestion: Have the lecture available in a separate window.


Enjoy learning by doing!


Point added for a correct answer:   
Points for a wrong answer:
Ignore the questions' coefficients:

1. Yes or No, The GCC box is also referred to as the AGC box.


2. The portion of the promoter in which an AGC box is likely to be found is which of the following?

core promoter
proximal promoter
downstream promoter
distal promoter

3. Yes or No, The AGC triplet repeat is found in the coding region of the human E2F-4 gene.



5. True or False, Some AGC boxes are located in the distal promoter.


6. Which of the following is not a transcriptional characteristic of AGC boxes?

in eukaryotes
TATA-less genes
a consensus sequence

7. Complete the text:

The AGC box is an -responsive element found in the of a large number of related genes whose expression is following pathogen attack.

8. Complete the text:

TATA box - A
initiator element - B
enhancers and inhibitors - C
downstream elements - D
General transcription factor II D - E
ATA box - F
downstream core promoter .
includes the transcription start site .
proximal promoter .
distal promoter .
core promoter
usually 25 nucleotides upstream .

9. Which of the following are phenomena associated with AGC boxes?

transcription of A1BG
directs activator-dependent but TFIID-independent transcription
TATA box-less promoters
initiator element
mediator dependence
distal promoter

10. True or False, AGC boxes are found in the promoter regions of at least 1% of human genes.


Your score is 0 / 0
