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. Transcription is a process that involves the transcribing of genetic information from DNA to RNA. There are three main steps to the process of transcription. First, DNA is transcribed by an enzyme called RNA polymerase. Specific nucleotide sequences tell RNA polymerase where to begin and where to end.here are three primary types of RNA involved in protein synthesis: messenger RNA, transfer RNA and ribosomal RNA. Messenger RNA. Whereas most types of RNA are the final products of their genes, messenger RNA (mRNA) is an intermediate in the information transfer process.
