What is the primary function of mRNA in protein synthesis?

• To carry amino acids to the ribosome

• To transport DNA out of the nucleus

• To deliver the genetic code from DNA to the ribosome

• To form the structure of the ribosome

Which component of the cell is responsible for the synthesis of proteins?

• Nucleus

• Ribosome

• Mitochondria

• Golgi apparatus

What is the role of tRNA during translation?

• To synthesize mRNA

• To transport amino acids to the ribosome

• To convert DNA into RNA

• To form peptide bonds

How does a tRNA molecule recognize the correct codon on mRNA?

• By forming a peptide bond

• By binding to the ribosome

• By matching its anticodon with the mRNA codon

• By using a codon chart

What does a stop codon signify during translation?

• The termination of the polypeptide chain

• The end of the mRNA strand

• The beginning of transcription

• The start of a new protein
