what stimulates the gene in order for transcription to begin?
transcriptonal factor moving from cytoplasm to nucleus
1 of 10
each transcriptional factor has a ...
site which binds to a specific region of DNA
2 of 10
the binding of the transcriptional factor to a specific region of dna ...
stimulates the DNA to begin transcription
3 of 10
what happens when a gene is not expressed?
site on transcriptional factor is blocked with an inhibitor molecule
4 of 10
how does the hormone oestrogen enter body cells?
it is lipid soluble so can diffuse across the cell surface membrane
5 of 10
what does oestrogen do once inside the cytoplasm?
it combines with a site on a receptor molecule of the transcriptional factor
6 of 10
what is the effect of oestrogen combining with the transcriptional factor?
it releases the inhibitor from the DNA binding site by changing its shape
7 of 10
the transcriptional factor can now...
enter the nucleus through a nuclear pore and combine with DNA
8 of 10
combination of transcriptional factor with DNA ...
stimulates transcription of the gene that makes up the portion of DNA
