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).
Very briefly, transcription is making messenger RNA (mRNA) from genomic DNA and translation is making protein from the mRNA Both involve enzymes (although different ones) that take various building blocks (nucleotides in the case of transcription and amino acids in the case of translation) and use them to string together a macromolecule.
