You are free to take this quiz based on the TATA binding protein associated factors 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


1 Yes or No, When there is no TATA box nucleotide sequence in the gene core promoter region of the DNA next to a gene, a TATA binding protein associated factor (TAF) will bind sequence specifically and force the TATA box binding protein to bind non-sequence specifically to the DNA in the 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 Yes or No, Let the symbol TAF stand for TATA binding protein associated factor.


4 True or False, The TATA binding protein associated factors are located in the distal promoter.


5 Which of the following are not a transcriptional characteristic of the TATA binding protein associated factors?

located between nucleotides -8 and +2 relative to the transcriptional start site (+1)
in eukaryotes
TATA-less genes
a consensus sequence

6 Yes or No, The catalysis of each RNA representation from the template DNA is a transcription, specifically a gene transcription.


7 Which of the following are phenomena associated with the TATA binding protein associated factors?

transcription of A1BG
directs activator-dependent but TFIID-independent transcription
TATA box-less promoters
initiator element
mediator dependence
core promoter

8 Yes or No, The TATA-binding protein (TBP) is a general transcription factor that binds specifically to a DNA sequence called the TATA box.


9 True or False, TATA binding protein associated factors are found in the promoter regions of about 1% of human genes.


10 True or False, A dominant group with respect to TAFs differs from a control group in that it rules the treatment of the control group.


Hypotheses edit

  1. TAFs are involved in the transcription of A1BG.
