• tRNA is a type of RNA that is folded into a specific three-dimensional structure. It carries and transfers an amino acid to the polypeptide chain that the ribosome is assembling. • One end of the tRNA contains an anticodon, a sequence of three nucleotides that is complementary to the three nucleotides in the corresponding codon on the mRNA.
Use the codon table to determine which amino acid will be carried by a tRNA, given the anticodon sequence. Identify untranslated regions and include these regions in gene diagrams. Explain how some antibiotics affect ribosomes to kill bacteria.
tRNA: Once the mRNA enters the ribosome, the anticodon on the tRNA binds to a specific mRNA codon (there are different types of tRNA molecules, each with its own anticodon, floating around the ribosome). Each anticodon on tRNA matches with a specific amino acid.
• Understand the structure and function of tRNA. • Understand the process in which the tRNA carries an amino acid. • Understand the components and structures of the ribosomes of prokaryotes and eukaryotes. • Understand the process of making the ribosome from genes to their final structure.
Apply the base-pairing rules to predict the nucleotide structure of RNA. Explain the use of mRNA, rRNA, and tRNA in the process of translation. Accurately use the codon table to predict the amino acid sequence of a protein.
