Regulation of Transcription and Translation Flashcards
1
Q
how does oestrogen enter the cell
A
because oestrogen lipid sopluble molecule so can diffuse through phospholipid bilayer and eneter the cytoplasm
2
Q
what does it do in the cytoplasmn
A
combine with a receptor site on the transcriptional factor
3
Q
why can it bind
A
the shape of the receptor site and the shape of oestrogen are complimentary to each other
4
Q
what happens when the oestrogen bind
A
it changes the shape of the dna binding site on the transcriptional factor which can now bind to dna so activated
5
Q
what happens to this transcriptional factor
A
it enter the nucleas through nuclear pire and bind to specific sequence of the dna stimulating transcription
