Gene transcriptions/Boxes/Xs/Quiz

X box is a lecture of the gene transcription series.

You are free to take this quiz based on the X 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 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
{Complete the text: The conserved GA response complex (GARC), a tripartite cis motif comprising the GA response element (GARE, 5'-TAACAAA-3'), the pyrimidine box (5'-CTTTT-3') and the TATC box (5'-{ TATCCAC (i) }-3'), all of which are necessary for a full { GA response (i) }.
 * type="{}"}

{Yes or No, The X box is a member of the GA responsive complex. - Yes + No
 * type=""}

{Several promoter elements have been previously identified in eukaryotes, but those cannot account for transcription from most RNA polymerase II-transcribed { genes|gene (i) }.
 * type="{}"}

{True or False, Consistent with its role as a transcriptional repressor, OsWRKY71 binds specifically to functionally defined TGAC-containing X boxes of the Amy32b promoter in electrophoretic mobility shift assays. - TRUE + FALSE
 * type=""}

{Complete the text: A short or { incomplete (i) } realization of a certain { method (i) } or idea to { demonstrate (i) } a treament's feasibility for TATA boxes is called a proof of { concept (i) }.
 * type="{}"}

{True or False, NPR1 is regulated by WRKY TFs interacting with two W box elements in its 5'-UTR. + TRUE - FALSE
 * type=""}

{Which of the following is not a transcriptional characteristic of X 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
 * type="[]"}

{True or False, Multiple W-boxes have a synergistic effect on transcription. + TRUE - FALSE
 * type=""}

{Which of the following are phenomena associated with X boxes? - transcription of A1BG - directs activator-dependent but TFIID-independent transcription + TATA box-less promoters - initiator element - mediator dependence + core promoter
 * type="[]"}

{True or False, Almost all WRKY transcription factors bind preferentially to W-boxes, and since their discovery, this has raised the question as to how they show specificity for the promoters of their target genes. + TRUE - FALSE
 * type=""}

{Although the X-box core is required, adjacent sequences also play a role in determining binding-site { preference (i) }.
 * type="{}"}

{True or False, The TGAC core is more degenerate, composed of a guanine adenine cytosine (GAC) core, and the upstream thymine and downstream pyrimidine flanking sequences help dictate recognition by specific WRKY factors. + TRUE - FALSE
 * type=""}

Hypotheses

 * 1) A TATC box is not used to transcribe A1BG.
 * 2) A W box is used to transcribe A1BG.
 * 3) An X box is used to transcribe A1BG.
