Proximal promoters is a lecture and an article as part of the gene transcription series.

You are free to take this quiz based on the proximal promoters 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 proximal sequence upstream of the gene that tends to contain primary regulatory elements is called a proximal promoter.

Yes
No

2

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

dispersed promoter
proximal promoter
downstream promoter
distal promoter
enhancer
focused promoter
core promoter

3

Yes or No, The genetic information in a genome is held within genes, and the complete set of this information in an organism is called its genotype.

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 proximal promoters are located in the dispersed promoter.

TRUE
FALSE

6

Which of the following is not a transcriptional characteristic of proximal 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

Complete the text:

The proximal

upstream of the

that tends to contain

regulatory

is a proximal promoter.

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
General transcription factor II D - 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 proximal promoters?

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

10

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

TRUE
FALSE


Hypotheses[edit]

Main source: Hypotheses
  1. The proximal promoter for A1BG is involved in enhancing or inhibiting only.
