Gene transcriptions/Elements/Downstream TFIIB recognitions/Quiz

Downstream TFIIB recognition element is a lecture as part of the gene transcription series.

You are free to take this quiz based on the downstream TFIIB recognition element 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
{Yes or No, A TFIIB recognition element (BRE) functions to determine the orientation of the TFIIB-TBP-TATA complex that projects the zinc ribbon of TFIIB toward the TSS. + Yes - No
 * type=""}

{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
 * type="[]"}

{Yes or No, The TFIIB-DNA contact with the BREd takes place via the minor groove, while that with the upstream B recognition element (BREu) takes place through the major groove. + 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="{}"}

{Yes or No, Some distal promoters are located in the dispersed promoter. - Yes + No
 * type=""}

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

{Complete the text: A distal promoter is a { distant (i) } (in numbers of nucleotides) portion of the { promoter|gene promoter (i) } for a particular { gene (i) }.
 * type="{}"}

{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 { D (i) }. includes the transcription start site { B (i) }. proximal promoter { F (i) }. distal promoter { C (i) }. core promoter { E (i) } usually 25 nucleotides upstream { A (i) }.
 * type="{}"}

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

{True or False, Downstream TFIIB recognition elements are found in the promoter regions of at least 1% of human genes. + TRUE - FALSE
 * type=""}

Hypotheses

 * 1) A1BG is not transcribed by a downstream TFIIB recognition element.
