When a negative transcription factor is added to the regulatory region of DNA, what happens?
choose all that apply a. RNA polymerase does not bind to the regulatory region to begin transcription. b. RNA polymerase binds loosely to the regulatory region and transcription begins. c. The negative transcription factor cannot bind to the regulatory region so it does not affect the action of RNA polymerase. d. mRNA is not produced due to the presence of the negative transcription factor.

What is a transcription factor?
regulatory proteins
What happens when a steroid hormonoe binds to a receptor?
acts as a transcription factor and binds to DNA, activating a gene
What is the role of the transactivation domain?
Transactivation domains are regions on a transcription factor (protein) which helps to activate transcription by contacting transcription factor. This is believed to be done to recruit the general transcription factors onto the gene promoter region.
What is the function of rho factor?
The rho factor acts to terminate bacterial transcription.
What is the function of the general transcription factor TFIID?
TFIID recognizes the TATA box.
Which molecule is primarily responsible for the differntiation of cells?
transcription factor proteins.
In a negative correlation as one factor is decreased the other factor?
In a negative correlation as one factor is decreased, the other factor is increased.
What is activated by a signal transduction pathway moved from the cytoplasm to the nucleus of a cell?
transcription factor
Will the product of a positive and a negative factor be a positive or negative value?
Negative
What is a negative scale factor?
A negative scale factor is used to produce the image on the other side of the centre of enlargement (scaled to the absolute value of the scale factor).
Can two negative blood factor parents create a negative blood factor baby?
Rh negative is a recessive trait but if both parents had it, then the children would have it.
In the binding of RNA polymerase to a gene requires the aid of a transcription factor?
Like prokaryotes, eukaryotes must regulate gene expression. This is accomplished primarily by controlling when RNA polymerase binds to the beginning of a gene. This binding cannot take place in eukaryotes without the aid of transcription factor.
