Downstream promoter elements is a lecture and an article from the biochemistry department and the genetics department. It is also part of the original research gene project.

You are free to take this quiz based on the downstream promoter elements 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 and the gene transcriptions course. 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 | edit source]

  

1 Yes or No, DPE-dependent basal transcription depends highly on the Inr (and vice versa) and on correct spacing between the two elements.

Yes
No

2 Yes or No, The core sequence of the DPE is located at precisely +28 to +32 relative to the A+1 nucleotide.

Yes
No

3 Yes or No, The core promoter elements such as DPE are trans acting elements.

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, The downstream promoter element is located in the distal promoter.

TRUE
FALSE

6 Which of the following is not a transcriptional characteristic of the downstream promoter element?

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 True or False, The downstream promoter element is upstream by about +40 nucleotides.

TRUE
FALSE

8 Which of the following are phenomena associated with the downstream promoter element?

transcription of A1BG
directs activator-dependent but TFIID-independent transcription
TATA box-less promoters
transcription start site
mediator dependence
core promoter
RNA polymerase II holoenzyme

9 True or False, The downstream promoter element is found in the promoter regions of about 1% of human genes.

TRUE
FALSE

10 True or False, The downstream promoter element is most likely to occur with the Inr.

TRUE
FALSE


Hypotheses
