You are free to take this quiz based on the CGCG boxes 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

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

No
Yes

2 The portion of the promoter in which an CGCG 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 CGCG duplet repeat is found in the coding region of the human CaM 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 CGCG boxes are located in the distal promoter.

FALSE
TRUE

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

G/A/T-G/C+1-G-T/C-G-G-G/A-A-G/C
in eukaryotes
TATA-less genes
a consensus sequence
located between nucleotides -8 and +2 relative to the transcriptional start site (+1)

7 Complete the text:

perception.

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
