DOGMA_GENE REGULATION
it is when to or not to express the gene
GENE REGULATION
aka housekeeping genes, always expressed and required for survival
CONSTITUTIVE GENES
genes expressed only when required
FACULTATIVE GENES
when and who proposed the operon hypothesis
1961, FRANCOIS JACOB AND JACQUES MONAD
components of an operon
STRUCTURAL GENES, OPERATOR, PROMOTER AND REGULATORY GENES
type of inducer operon system
LAC OPERON SYSTEM
structural genes of a lac operon
LAC Z,Y,A
it is where the RNA polymerase binds
PROMOTER
it is the one that controls the transcription to occur or not
OPERATOR
regulatory protein that binds to the operator to turn it off
LAC REPRESSOR
it binds to the repressor to inactivate it
LAC INDUCER
