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).
Report Abuse. Transcription factors are protein complexes that help RNA polymerase bind to DNA. RNA polymerase is the enzyme that transcribes genes to make messenger RNA, which is then used to make protein.By controlling RNA polymerase's access to the gene, transcription factors control the rate at which a gene is transcribed.Without transcription factors, cells would not be able to effectively regulate the rate at which genes are expressed.hat is the function of transcription factors in eukaryotic cells? A. They control the expression of certain genes. B. They bend the DNA to bring it close to the operator.
