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).
What is the role of mRNA and tRNA in the production of protein? mRNA: Transcription copies the information stored in the nuclear DNA into complementary code in the messenger RNA (mRNA). The mRNA then leaves the nucleus and moves into the â¦cytoplasm. Ribosomes attach to the mRNA and start to translate the information contained in the mRNA into a sequence of amino acids.
