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, and in the course 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.

A suggestion is to 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

Point added for a correct answer:   
Points for a wrong answer:
Ignore the questions' coefficients:

1. 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

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 EIF4E basal elements are located in the dispersed promoter.

TRUE
FALSE

4. 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

5. Complete the text:

The location of the 4EBE is at the site where the box should be .

6. 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 .

7. 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

8. True or False, EIF4E basal elements are found in the promoter regions of at least 1% of human genes.

TRUE
FALSE

Your score is 0 / 0

Research

Hypothesis:

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

Control groups

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
