gene expression in eukaryotes Flashcards
Compare and contrast gene regulation prokaryotic and eukaryotes
you should know
structural and organization differences
explain transcription factors and post transcriptional
how does gene expression work in eukaryotes
Are there any advantages to having transcription and translation occur in separate places.
More time to see mistakes/ errors. very flexible
how many RNA polymerases does Prokaryotes and eukaryotes have.
P:1 E:3
Structal proteins that organize DNA ?
Histones . This is how eukaryotes cells manage their genes
modifiers? hint- kinda postive?
activators, enhancers , repressors, sileners
What occur pre transcription
histones and the wrapping of DNA
Go through the major differences between prokaryotes and eurkaryotes. Yes we talked about it before but say them again. Promoters, mRNA processing etc.
All the steps for pre transcription
Do all genes have the TATA box
NO
Helix turn helix motif
found in many DNA binding proteins and fits into major grooves
if transcription factors are genes that regulate other genes how are transcription factors regulated
By other proteins and processing
stress response element
expression to be activated at the same time at the available sites
