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
Transfer RNA. Transfer RNA (tRNA) is a stable molecule that exists in complex folded structures. It acts as an adapter to translate the nucleotide sequence of mRNA into protein sequence. It does this by carrying the appropriate amino acid to the ribosome during the process of protein synthesis.rotein synthesis requires a technical machinery of high complexity. The journey from DNA to RNA to protein is tightly controlled within each cell. Protein synthesis consists of two major steps â transcription and translation â and primarily uses three types of RNA â messenger RNA, transfer RNA and ribosomal RNA.
