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 is the first of overall two protein synthesis steps. During transcription, the information encoded in the DNA is copied to a RNA molecule as one strand of the DNA double helix is used as a template. The RNA molecule is sent to the cytoplasm, which helps to bring all components required for the actual protein synthesis together â amino acids, transport RNAs, ribosomes, etc.
