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 process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. The genes in DNA encode protein molecules, which are the workhorses of the cell, carrying out all the functions necessary for life.
