Anaphylaxis: A life-threatening reaction. Peanut allergy is the most common cause of food-induced anaphylaxis, a medical emergency that requires treatment with an epinephrine (adrenaline) injector (EpiPen, Auvi-Q, Twinject) and a trip to the emergency room. Anaphylaxis signs and symptoms can include: Constriction of airways.
Initiation of Transcription in Eukaryotes. Initiation is the first step of eukaryotic transcription and requires RNAP and several transcription factors to proceed.
Transcription & Translation: Transcription (Advanced). Transcription is the process by which the information in DNA is copied into messenger RNA (mRNA) for protein production. Transcription begins with a bundle of factors assembling at the promoter sequence on the DNA (in red).Here, two transcription factors are already bound to the promoter.ther proteins arrive, carrying the enzyme RNA polymerase (in blue). To initiate transcription, these assembled proteins require contact with activator proteins that bind to specific sequences of DNA known as enhancer regions. Once the contact is made, the RNA polymerase races along the DNA to transcribe the gene.
