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).
Roles of Ribosomes. Messenger RNA carries a copy of the genetic code for a certain protein, which it copied from DNA. The code specifies specific amino acids, which must be linked together in a certain order to manufacture a specific protein. The mRNA must bind to a ribosome before the translation process can begin. Transfer RNA is responsible for reading the message and bringing the correct amino acids to the ribosome according to this code. Each tRNA carries a distinct amino acid, and attaches it to the growing protein chain.
