WHAT IS IEC 60601-1. IEC 60601 is a series of technical standards. for the safety and effectiveness of medical. electrical equipment. The primary standard governing medical device. design is IEC 60601-1 (medical electrical equipment. - Part 1: general requirements for basic safety and. essential performance).
Figure 1: A gene is expressed through the processes of transcription and translation. 1  During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink).
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.
