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
â tRNA molecules (transfer RNA) are âtranslatorâ molecules; they can match the appropriate amino acid with the codon in the mRNA. Part of the molecule binds an amino acid, and the other end has three nucleotides (anticodon) that form a base pair with the codon in the mRNA. Translation â¢ Steps in Translation.
