Put the following events of translational elongation (the stage in translation that occurs after initiation) in the order that they occur, beginning with the first step at the top. Instructions The ribosome releases the second tRNA. The ribosome releases the first tRNA. A covalent bond forms between the first and second amino acids. After the first amino acid has been brought to the ribosome, a tRNA carrying the second amino acid of a protein binds to the second codon.

Put the steps in translation in order. The names of the enzymes and the names of the strands are highlighted to help you see the order in which they work. The ribosome dissociates into the 30S and 50S subunits and the messenger RNA and protein are released. tRNAs continue to move into the A site, amino acids are joined, and "empty" tRNAs leave the ribosome until a stop codon moves in the A site. The ribosome advances a distance of one codon and the tRNA that carried the formyl-methionine is released at the E site. The formyl-methionine carried by the tRNA in the P site is then joined to the amino acid carried by the tRNA in the A site by a peptide bond. A tRNA that recognizes the next codon and carries the second amino acid moves into the A site of the ribosome. An initiation complex is formed, consisting of the 30S ribosomal subunit, a tRNA carrying formyl-methionine, mRNA, and the 50S ribosomal subunit.

Put the following events in the order they occur during translation. One event is NOT part of translation, do NOT include it in your sequence. The finished polypeptide, mRNA, and ribosomal subunits separate. A peptide bond is catalyzed between the first and second amino acids. The ribosome moves so that the third codon is in the A site. A second tRNA with brings in the second amino acid. The small ribosomal subunit associates with the mRNA and moves to the correct start location. The stop codon enters the A site. Translation starts by adding the amino acid that corresponds to the codon at the 5' end of the mRNA. Translation starts when tRNA carrying methionine associates with the first AUG from the 5' end of the mRNA.

Steps in Translation: Start codon signals mRNA to bind to the small subunit of the ribosome. Initiator tRNA (with the amino acid methionine) attaches its anticodon to the mRNA site of the ribosome. The large and small subunits of the ribosome join. mRNA is threaded through the ribosome. The 2nd tRNA (with an amino acid) binds its anticodon with the mRNA's codon in the site of the ribosome. A bond forms between 2 amino acids. The polypeptide chain is transferred to the tRNA in the A site, and the 1st tRNA moves to the E site and is released. The tRNA with the growing polypeptide chain moves from the site. Elongation continues until the codon reaches the A site. The ribosome splits apart, and the polypeptide chain is released. The protein folds and becomes functional (active).
