Regulation of Gene Expression Flashcards
1
Q
Levels of control
A
transcriptional, RNA processing, RNA transport and localization, mRNA degradation, translational, protein activity control
2
Q
Promotor
A
RNA Pol II and TF bind to DNA upstream
3
Q
Enhancer
A
DNA where regulatory proteins increase expression
4
Q
Silencer
A
DNA locus where regulatory proteins decrease expression
5
Q
DNA methylation
A
mutes DNA
6
Q
histone methylation
A
transcriptional repression
7
Q
histone acetylation
A
relaz DNA coiling, more transcription
8
Q
histone deacetylation
A
tightens DNA coiling
9
Q
Prokaryotic control
A
Positive and negative control (lactose)
negative for Trp
10
Q
Eukaryotic Gene Regulation
A
Coordinate regulation:
Hormone response system (intracellular or cell surface)
11
Q
Regulation through DNA
A
access, amount, arrangement of DNA
mobile DNA elements
