Genetic Regulation Flashcards
Regulatory Protiens
control gene expression by binding to specific sites on DNA and turning transcription on/off/up
External signals
an turn gene expression on and off
Patterns of regulation
applicable to different genes
different regulatory mechanisms
can control same gene
Cloning issue
nuclear transplantation requires dedifferentiation, which results in increased methylation
General transcription factors
proteins required to start transcription, varying factors affect which genes are transcribed
Post Translation
folding
transportation
polypeptide modification
metaboloc regulation/activation
Cell signaling
regulate activities
turn genes on and off
shape
division and death
cell to cell communication
Reception
target cell detects signal molecule
(binds to receptor)
Transduction
signal converted along signal transduction pathway (phosphorylation cascade)
Response
Cellular response occurs
Induction
cells influence the development of neighbors through close interactions
