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).
The purpose of transcription is to produce a protein with a  specific function.    DNA is copied into a strand of mRNA and mRNA is read and copied  into a protein to â¦ carry out some function for the cell.    It is the first step in protein synthesis.    /  .2 people found this useful. Because DNA is a much stable molecule than RNA. However, in many viruses genetic information is encoded in their RNA. Consequently, these viruses mutate at a very high r â¦ ate and change constantly to avoid onslaught from the host's immune system.
