Document Summary
Topic b: you are an amino acid in the lumen of the small intestine. You are looking at transporter proteins protruding from the apical surfaces of the intestinal epithelial cells. Your addition is to be part of one of those membrane transporters. Translation is the synthesis of a protein from a mrna complex, and is divided into 3 stages, which are initiation, elongation, and termination. The initiation stage of translation is the process where mrna, initiator trna, and small and large ribosomal units interact with each other to form a complex. The mrna is read using the genetic code, and takes the dna and rna sequence to convert it to a amino acid sequence, which in turn results in various proteins. To do this, trna molecules are used to match amino acids to codons in the mrna because codons do not just automatically pair up to its matching amino acid.
