Gene Expression
Regulatory gene
Operons
Types of cells
Molecules,Enzymes, and
Proteins
lactose operon
inductible operon
can be switched off by the
lac repressor, which is
active by itself
inducer
repressor
promoter
corepressor
these genes are expressed
continuously and at a low rate,
they also create the repressor
Prokaryotic
Eukaryotic
a single-celled organism
that has a nucleus but no
organelles
cells found in multicellular
organisms that have a
nucleus and organelles
activator
differential gene
expression
a small molecule that
inactivates the repressor
an operon whose synthesis is
induced by a chemical signal
a small molecule that works
together with the repressor to
switch an operon off
binds to the operator and blocks
attachment of RNA ploymerase to
the promoter, preventing the
transcription of genes
a protein that binds to
DNA and stimulates
transcription of a gene
a site where RNA polymerase
binds to DNA and begins
transcription
the expression of different
genes by cells with the same
genome
operator
an "on-off switch" that controls a
cluster of functionally related
genes, it controls the access of
RNA polymerase to the genes
the operator, the
promoter, and the
genes they control
make up an operon
mutation in regulatory gene
a mutation may lead to the
increased production of a certain
gene, which can lead to cancer
