Distal promoter is a lecture and an article as part of the gene transcription series.

You are free to take this quiz based on the distal promoter 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 | edit source]

  

1 Yes or No, A distal promoter is a distant (in numbers of nucleotides) portion of the promoter for a particular gene.

Yes
No

2 The portion of the promoter in which a distal promoter is likely to be found is which of the following?

dispersed promoter
proximal promoter
downstream promoter
distant promoter
enhancer
focused promoter

3 Yes or No, A distal promoter is upstream of the 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 distal promoters are located in the dispersed promoter.

TRUE
FALSE

6 Which of the following is not a transcriptional characteristic of distal promoters?

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 Yes or No, A distal promoter is a region of DNA that may contain additional regulatory elements, often with a weaker influence than the proximal promoter.

Yes
No

.
core promoter

usually 25 nucleotides upstream

.

10 Which of the following are phenomena associated with distal promoters?

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

11 Yes or No, Distal promoters are found in the promoter regions of at least 1% of human genes.

Yes
No


Hypotheses[edit | edit source]

  1. There may be additional genes in at least one of the distal or pre-promoter regions of A1BG.
