Protein Synthesis Quiz

What is the initial step in protein synthesis where a DNA template is used to form mRNA?

• Mutation

• Replication

• Transcription

• Translation

Which molecule carries amino acids to the ribosome during translation?

• DNA

• tRNA

• rRNA

• mRNA

What is the role of a start codon in the process of translation?

• It signals the end of protein synthesis.

• It codes for the first amino acid in a protein.

• It adds a poly A tail to mRNA.

• It removes introns from mRNA.

In eukaryotic cells, where does transcription occur?

• In the nucleus

• On the ribosomes

• In the cytoplasm

• On the cell membrane

How do prokaryotic cells differ from eukaryotic cells in terms of protein synthesis?

• Prokaryotic cells process mRNA before translation.

• Prokaryotic cells have introns in their genes.

• Prokaryotic cells perform transcription and translation simultaneously.

• Prokaryotic cells have compartmentalized transcription and translation.
