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).
Transcription is the first step of gene expression, in which a  particular segment of DNA is copied into RNA (mRNA) by the enzyme  RNA polymerase.Both RNA and DNA are nucle â¦ ic acids, which  use base pairs of nucleotides as a complementary language.he two main steps in gene expression are transcription and translation. In eukaryote cells transcription occurs in the nucleus, and translation occurs in the cytoplasm. 1 person found this useful. Edit.
