Protein Synthesis Quiz

What is the first stage of protein synthesis where RNA polymerase attaches to DNA?

• Elongation

• Initiation

• Termination

• Translation

Where does mRNA travel after being synthesized in the nucleus?

• To the mitochondria

• To the ribosome

• To the Golgi apparatus

• To the lysosome

What are the two major components of a ribosome?

• Amino acids and proteins

• Small subunit and large subunit

• Nucleus and cytoplasm

• DNA and RNA

What is the role of a codon during translation?

• It signals the start of transcription

• It forms a peptide bond

• It folds the protein into its final shape

• It pairs with an anticodon on tRNA

What happens when a stop codon is reached during translation?

• The mRNA is destroyed

• The polypeptide chain is released

• The ribosome disassembles

• The tRNA is recycled
