Operon
100
A region of DNA that initiates transcription of a particular gene.
What is a promotor
100
Located in thousands of base pairs away from the gene that they regulate.
What is silencer
100
Binds sequence specifically to a DNA site located in or near a promotor.
What is activator
100
Definition
What is functioning unit of genomic DNA containing a cluster of genes under the control of a single promoter.
200
Controlled sections of DNA
What is silencer
200
Located near the transcription start sites for genes.
What is promotor
200
Operates by binding to the major groove of the operator region of the lac operon.
What is repressor
200
What is the location of the operon?
What is the cytoplasm
300
Short regions of DNA that can be bound with proteins.
What is Enhancers
300
Location is DNA or RNA
What is repressor
300
Proteins that regulate the rate of the transcription of genes
What is transcription factors
300
What is the job of the operon?
What is enables organisms to regulate the expression of various genes depending on environmental conditions
400
A binding protein that inhibits the expression of one or more genes by binding to the operator.
What is repressor
400
At the beginning of the lac operon of the bacterium escherichia coil (e. Coli)
What is activator
400
needed for RNA polymerase to bind to initiate transcription
What is promotor
400
When was the operon discovered?
What is the early 1990s
500
A protein that binds to specific DNA sequences
What is transcription factors
500
May be located upstream or downstream from the gene it is regulating
What is enhancer
500
protein can bind to this site which helps RNA polymerase bind to the promotor. This can increase the amount of transcription that occurs.
What is an activator
500
By whom was the operon discovered by?
What is Jacob, Lwoff, Monod
