Translation DNA mRNA Ribosomal subunit tRNA Translation Protein Anticodon continues. Ribosomal subunit mRNA Components needed to begin translation come togettler. Figure 8.10.1
Translation Figure 8.10.1
Translation Ribosome continues. Start Second codon codon mRNA ② On the assembled ribosome,a tRNA carrying the first amino acid is paired with the start codon on the mRNA. A tRNA carrying the second amino acid approaches. Figure 8.10.2
Translation Figure 8.10.2
Translation Peptide bond forms P site Me A site continues. mRNA The place on the ribosome where the first tRNA sits is called the P site.In the A site next to it,the second codon of the mRNA pairs with a tRNA carrying the second amino acid. Figure 8.10.3
Translation Figure 8.10.3
Translation tRNA released Peptide bond AUGAUUAG continues. The first amino acid joins to the second by a peptide bond,and the first tRNA is released. Figure 8.10.4
