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 production of proteins involves two major steps: transcription and translation. Together, transcription and translation are known as gene expression. The process of transcription only involves two molecules: DNA and RNA. A DNA strand provides a template for the synthesis of a complementary RNA strand. This process is used to synthesize any type of RNA from a DNA template. Transcription of a gene produces a messenger RNA (mRNA) molecule.
