The Lac Operon
The Lac operon is this kind of operon.
What is an inducible operon?
The Trp operon is this kind of operon.
What is a repressible operon?
Vampires love drinking the blood of their victims, which contain this special oxygen-carrying protein!
What is hemoglobin?
This involves the use of activator proteins.
It's the pathway for Central Dogma.
What is DNA->RNA->Protein?
This is where active CAP binds to the operon
What is the Promoter?
Tryptophan is this kind of molecule, which binds a repressor to activate it.
What is a corepressor?
This spore-producing parasite can turn an ant into a zombie just in time for Halloween!
What is a fungus (aka cordyceps fungi)?
Cells don't express every gene because different cells in a multicellular organism express different proteins, which is known as this.
What is cell specialization?
This is the process of copying DNA into a single stranded mRNA molecule.
Transcription
These are the conditions in which no mRNA from the Lac operon are being transcribed
What is High/Low Glucose, Low Lactose?
The Trp operon is normally this due to the presence of a repressor but no corepressor.
What is on?
While Victor Frankenstein used a "spark of life" on his famous monster, modern paramedics use this life saving device to shock your heart back into a normal rhythm.
What is an AED (automated external defibrillator)?
What the repressor protein binds to when it is active.
What is the operator?
The type of mutation shown below:
Hap pyH all owe en! ->
Hap pya llo wee n!
What is a frameshift mutation?
This protein binds to the repressor and inactivates it when there are high levels of Lactose.
What is an allolactose inducer?
This bacteria containing a Trp operon (and a Lac operon). Helpful strain of it live in your stomach and aid in digestion but harmful strains can cause food poisoning.
What is E. coli?
Something a werewolf could get, this disease often comes with a fear of water. There are also two types: paralytic or furious.
What is rabies?
A promoter, operator, and structural genes make up this.
What is an operon?
This is what RNA processing receives on the 5' end and the 3' end.
What is a 5' Cap and a poly-A tail?
A bacterial cell containing lactose and lacking adenylate cyclase would be unable to efficiently express the lac operon because it cannot produce this signaling molecule.
What is cAMP?
Transcription occurs in the Trp operon when Tryptophan levels are this.
What is low?
A skeleton on Halloween night better protect this s-shaped bone because it is the most frequently broken bone in the human body.
What is the clavicle (or collarbone)?
The process through which the product of a pathway inhibits the same pathway by binding an enzyme.
What is Feedback inhibition?
During protein translation, this is the site where the tRNA enters the ribosome carrying an amino acid to match the codon.
What is the A site?
