Quiz edit


1 Yes or No, A transcription factor is a protein that binds to specific DNA sequences to control the flow (or transcription) of genetic information from DNA to messenger RNA (mRNA).


2 True or False, A dominant group associated with transcription factors differs from a control group in that it rules the treatment of the control group.


3 Several promoter elements have been previously identified in eukaryotes, but those cannot account for transcription from most RNA polymerase II-transcribed

4 Yes or No, A branch of biology that deals with the transmission and variation of inherited characteristics, in particular chromosomes and DNA is called genetics.


5 True or False, Some transcription factors are located in the distal promoter.


6 Which of the following is not a transcriptional characteristic of transcription factors?

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

7 Yes or No, Once the DNA double helix and its associated epigenome have been melted so that the template strand is available for binding, a transcription factor binds to a specific nucleotide sequence to biochemically influence gene transcription.


8 Which of the following are phenomena associated with transcription factors?

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

9 Yes or No, A coactivator is a protein that works with transcription factors to increase the rate of gene transcription.


10 True or False, Transcription factors are found in the promoter regions of at least 1% of human genes.


11 Evidence that demonstrates that a model or idea versus a control group is feasible with respect to transcription factors is called a


12 True or False, A general transcription factor is a special kind of transcription factor.


Hypotheses edit

  1. Transcription factors are not involved in the transcription of A1BG.
