Lab coats may or may not be considered PPE, depending on whether the fabric they are made out of is fluid resistant. If lab coats are fluid resistant and provide coverage in the form of high necks, etc., they can be considered PPE. The lab coats would have to be worn during procedures in which a splash/spray exposure could be expected.
-forms an important part of both subunits of the ribosome What is the role of tRNA? -carries amino acids to the ribosome and matches them to the coded mRNA message
The interaction of tRNA and mRNA in protein synthesis. A transfer RNA (abbreviated tRNA and archaically referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length, that serves as the physical link between the mRNA and the amino acid sequence of proteins. The amino acid loaded onto the tRNA by aminoacyl tRNA synthetases, to form aminoacyl-tRNA, is covalently bonded to the 3'-hydroxyl group on the CCA tail. 2  This sequence is important for the recognition of tRNA by enzymes and critical in translation.
