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).
Translation requires several enzymes and factors for the process. It has mainly three steps, initiation, elongation and termination each of which requires a set of RNAs, cofactors and enzymes. Siteâ Transcription generally occurs in the nucleus where the transcription factors and enzymes are available. Translation on the other hand occurs in the cytoplasm after the primary mRNA transcript is transferred from the nucleus to the cytoplasm.
