What does the addition of methyl groups to DNA cause?
Block RNA polymerase from attaching to DNAorcan directly switch off gene expression by preventing transcription factors from binding to promoters, segments of DNA that promote expression of a particular gene.
What do regulatory elements in gene control interact with?
transcription factors.
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 the TATA box?
The TATA box assists in directing RNA polymerase II to the initiation site downstream on DNA. RNA polymerases bind to regions of DNA known as promoters. Promoter regions are comprised of the initiation site and numerous nucleotides upstream from the initiation site. The TATA box is necessary for transcription because RNA polymersase II cannot recognize the initiation sites on its own.
What affects expression of specific cellular RNAs in the fast growing liver cells of an infant?
nuclear transcription factors
Examples of a molecule in your body that can affect transcription factors?
A repressor, which works by binding to the operator and blocking the attachment of RNA polymerase to the promoter.

What are a group of proteins that bind to the promoter or enhancer sequences to facilitate the binding of RNA polymerase to the promoter?
transcription factors
What role do transcription factors play in cell?
By binding to a plasma membrane receptor it initiates a cascade in a signal transduction pathway. They can activate yet more genes.
Where are transcription factors made?
Some transcription factors are proteinacious , they are synthesized in ribosomes .
What has the author Kenneth Maiese written?
Kenneth Maiese has written: 'Forkhead transcription factors' -- subject(s): Forkhead transcription factors, Forkhead Transcription Factors, Physiology
During protein synthesis in eukaryotic cells does the activator-enhancer complex the molocule of DNA so other transcription factors have better acces tothe bonding sites on the operator?
Yes. If I understand your question correctly (I cleaned up the wording slightly). Activators are proteins that bind to enhancer regions of DNA. This facilitates the binding of transcription factors and the RNA Polymerase to read the DNA of the gene.
What kind of organisms use transcription factors?
Eukaryotes
Which is true of transcription factors?
They control which genes are expressed.
