There is one start codon which also codes for methionine and are three stop codon that code not for amino acids but for the end of translation. Shown above is a prokaryotic ribosome. A ribosome is a tiny organelle composed of ribosomal RNAs and ribosomal proteins. The 50S ribosomal subunit is added, forming the 70S initiation complex. Figure 9.08 from textbook.
Antibiotics are substances of biological origin that kill bacteria.
A sampler of antibiotics that work by inhibiting translation is shown above.
