ATA box is a lecture as part of the gene transcription series.

You are free to take this quiz based on the ATA box 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 The portion of the promoter in which an ATA box is likely to be found is which of the following?

core promoter
proximal promoter
downstream promoter
distal promoter
enhancer

2 Several promoter elements have been previously identified in eukaryotes, but those cannot account for transcription from most RNA polymerase II-transcribed

3 True or False, Some ATA boxes are located in the distal promoter.

TRUE
FALSE

4 Which of the following is not a transcriptional characteristic of AGC boxes?

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

5 Complete the text:

The ATA box is a

6 Yes or No, ATA boxes [AATAAA] can be clearly identified in the chicken αA- and αD-globin genes about 70 bp upstream from the initiator ATG codon.

Yes
No

7 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

ATA box - F
downstream core promoter

.
includes the transcription start site

.
proximal promoter

.
distal promoter

.
core promoter

usually 25 nucleotides upstream

.

8 Yes or No, The 3' flanking area contained the highly conserved hexanucleotide sequence A-A-T-A-A-A found in eukaryotic messages between the terminator codon and the polyadenylylation site (44).

Yes
No

9 Which of the following are phenomena associated with ATA boxes?

transcription of A1BG

mediator dependence
distal promoter

10 True or False, ATA boxes are found in the promoter regions of at least 1% of human genes.

TRUE
FALSE
