Protein synthesis
Translation
Things to know…
• Structure and function of tRNA
• Structure and function of ribosome
• Stages of translation
– Initiation
– Elongation
– Termination
• Types of RNA
• Mutations can change products

DO NOW: on small paper
• Identify the difference(s)
between ribosomes in
cytoplasm and on ER.
• Can cytoplasmic and ER
ribosomes ever change
places? If so, when?
