You are free to take this quiz based on the TCEs 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


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


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

core promoter
proximal promoter
downstream promoter
distal promoter

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


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 TCEs are located in the distal promoter.


6 Which of the following is not a transcriptional characteristic of TCEs?

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

7 Complete the text:

The sequence

interacts with SM22α and SM-MHC proteins, and this

, or variations of it, was observed in all the selected DNA


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
T box - 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 TCEs?

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

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


Hypotheses edit

  1. A1BG is not transcribed using a TCE.
