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 type of RNA used during transcription is the messenger RNA. The mRNA carries a genetic message from â¦ the DNA to the protein-synthesizing machinery of the cell. Then, translation is the actual synthesis of a polypeptide, which occurs under the direction of mRNA.he type of RNA that copies DNA is known as the messenger RNA or mRNA. There are other types of RNA these include the transfer RNA (tRNA), and the ribosomal (rRNA).
