Initiation mRNA binds to the small subunit of the ribosome. The large subunit of the ribosome binds to the tRNA and The mRNA contains a series of codons (3 bases) each of which small subunit codes for an amino acid. Elongation A second tRNA (with amino acid attached) complementary to the second codon on the mRNA then binds to the A site of the ribosome charged tRNA contains energy in the bond with the amino acid Another tRNA binds, complementary to the next codon on attached which will be used to form the peptide bond. the mRNA, binds to the A site. There are three binding sites on 6, 7, and 8 are repeated until a stop codon is the large subunit of the ribosome, but only two can contain tRNA reached. molecules at a time. Termination When a stop codon is reached translation is stopped: 7.3.U6 Translation can occur immediately after transcription in prokaryotes due to the absence of a nuclear membrane. State two reasons why translation can occur immediately after transcription in prokaryotes.
