Metal responsive elements is a lecture as part of the gene transcription series.

You are free to take this quiz based on the lecture metal responsive 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. 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, The metallothionein (MT) genes provide a good example of eucaryotic promoter architecture.

Yes
No

2 The portion of a promoter in which an metal responsive element 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, MT genes specify the synthesis of low-molecular-weight metal-binding proteins.

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 metal responsive elements are located in the dispersed promoter.

TRUE
FALSE

6 Which of the following is not a transcriptional characteristic of metal responsive 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 Complete the text:

The metal ion

of metallothionens is conferred by a

sequence element called the

-responsive element

or TGC

.

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 metal responsive elements?

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

10 True or False, Metal responsive elements are found in the promoter regions of at least 1% of human genes.

TRUE
FALSE


Hypotheses[edit | edit source]

  1. A1BG is not transcribed by a metal responsive element.
