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.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{gene project}} template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz[edit]

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.

Yes
No

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
enhancer

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

Yes
No

4. Several promoter elements have been previously identified in eukaryotes, but those cannot account for transcription from most RNA polymerase II-transcribed


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

TRUE
FALSE

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

located between nucleotides -8 and +2 relative to the transcriptional start site (+1)
G/A/T-G/C+1-G-T/C-G-G-G/A-A-G/C
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:

Match up the type of promoter or promoter element with each of the possibilities below:
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.

TRUE
FALSE
