EIF4E basal element is a lecture and an article as part of the gene transcription series.

You are free to take this quiz based on the EIF4E basal 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, The EIF4E basal element, also eIF4E, (4EBE) is a basal promoter element for the eukaryotic translation initiation factor 4E. + Yes - No
 * type=""}

{The portion of a promoter in which an EIF4E basal element is likely to be found is which of the following? - dispersed promoter + proximal promoter - downstream promoter - distal promoter - enhancer - focused promoter + core promoter
 * type="[]"}

{Yes or No, Interactions between 4EBE and upstream activator sites are position, distance, and sequence dependent. + 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, Some EIF4E basal elements are located in the dispersed promoter. - TRUE + FALSE
 * type=""}

{Which of the following is not a transcriptional characteristic of EIF4E basal 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
 * type="[]"}

{Complete the text: The location of the 4EBE is at the site where the { TATA (i) } box should be { found (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 EIF4E basal elements? - transcription of A1BG - directs activator-dependent but TFIID-independent transcription - TATA box-less promoters - initiator element - mediator dependence + core promoter
 * type="[]"}

{True or False, EIF4E basal elements are found in the promoter regions of at least 1% of human genes. + TRUE - FALSE
 * type=""}

Hypotheses

 * 1) A1BG is not transcribed by an eIF4E basal element.
