What is the primary function of tRNA (transfer RNA) during protein synthesis?

• Binding to mRNA

• Carrying amino acids

• Forming ribosomes

• Initiating translation

Where does translation occur within a cell?

• Nucleus

• Ribosome

• Endoplasmic reticulum

• Mitochondria

Which molecule carries the genetic code from the nucleus to the ribosome?

• mRNA

• tRNA

• rRNA

• DNA polymerase

What is the start codon that initiates protein synthesis?

• UAG

• UAA

• AUG

• UGA

What is the role of ribosomes in protein synthesis?

• Synthesizing mRNA

• Carrying amino acids to the ribosome

• Catalyzing the formation of peptide bonds

• Carrying DNA to the cytoplasm

During translation, what occurs in the ribosome?

• Amino acids are linked to form a polypeptide chain

• mRNA is converted back to DNA

• tRNA is replicated

• DNA is transcribed to mRNA

Which of the following is not involved in protein synthesis?

• DNA helicase

• Ribosome

• mRNA

• tRNA

What is the function of the stop codon in mRNA during translation?

• Marks the beginning of translation

• Initiates the binding of tRNA to the ribosome

• Signals the end of protein synthesis

• Encodes an amino acid

What happens during the elongation stage of translation?

• Ribosome binds to mRNA

• Amino acids are added to the growing polypeptide chain

• tRNA is released from the ribosome

• mRNA is transcribed into tRNA
