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

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

TRUE
FALSE

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.
