You are free to take this quiz based on downstream core 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

  

1 Yes or No, Lower down, in relation to a river or stream following the path of a river or stream is called downstream.

Yes
No

2 Yes or No, The downstream core element (DCE) is a transcription core promoter sequence that is within the transcribed portion of a gene.

Yes
No

3 Yes or No, The core promoter elements such as DCE 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 core elements are located in the distal promoter.

TRUE
FALSE

6 Which of the following is not a transcriptional characteristic of the downstream core elements?

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 core elements are upstream by about +40 nucleotides.

TRUE
FALSE

8 Which of the following are phenomena associated with the downstream core elements?

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 core elements are found in the promoter regions of about 1% of human genes.

TRUE
FALSE

10 True or False, The downstream core elements are most likely to occur with the Inr.

TRUE
FALSE


Hypotheses

Main resource: Hypotheses
  1. The downstream core elements (DCEs) are not involved in the transcription of A1BG.
