What happens when a steroid hormonoe binds to a receptor?
acts as a transcription factor and binds to DNA, activating a gene
Which molecule is primarily responsible for the differntiation of cells?
transcription factor proteins.
What is activated by a signal transduction pathway moved from the cytoplasm to the nucleus of a cell?
transcription factor
What is the primary function of a transcription factor?
To ensure that a gene is used at the right time and that proteins are made in the right amounts.
What are the proteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter called?
transcription factor
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 a transcription factor?
regulatory proteins
What molecule is formed during eukaryotic transcription?
mRNA is generated as a result of transcription.
What is the function of rho factor?
The rho factor acts to terminate bacterial transcription.
What are the end results in transcription and translation?
Transcription yields a strand of messenger RNA, which then goes to the ribosomes, where it undergoes translation by transfer RNA, and the absolute end result is a protein.
When a negative transcription factor is added to the regulatory region of DNA, what happens?
DNA
What happens when a steroid hormonoe binds to a receptor?
acts as a transcription factor and binds to DNA, activating a gene
If a strand of DNA has the sequence aagctc transcription will result in?
TTCGAG
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.
What is the result of Transcription?
DNA is converted to a strand of mRNA to be translated in the ribosome.
What causes longer clotting time?
The main cause of a longer clotting time is the deficiency of the clotting factor in the blood. This is as a result of a damaged platelet in the blood cells.
