What is the function of a codon in protein synthesis?

• Releases the newly synthesized polypeptide

• Breaks the bond holding tRNA to its amino acid

• Forms a peptide bond

• Specifies a particular amino acid

Which codon serves as the 'start' codon for protein synthesis?

• AUG

• UCU

• CAC

• AAC

What is the process that produces proteins by decoding the sequence of mRNA codons?

• Transcription

• Mutation

• Translation

• Replication

Which of the following is NOT involved in the process of translation?

• DNA

• rRNA

• tRNA

• mRNA

What is the role of tRNA in protein synthesis?

• Transports amino acids to the ribosome

• Forms peptide bonds between amino acids

• Decodes the mRNA codons

• Initiates protein synthesis

What is the function of the ribosome in protein synthesis?

• Transcribes DNA into mRNA

• Translates mRNA into a polypeptide chain

• Replicates DNA strands

• Edits mRNA for accuracy

What is the function of the anticodon in tRNA during protein synthesis?

• Initiates translation process

• Matches with the mRNA codon

• Forms peptide bonds

• Releases the polypeptide chain

Which organelle is primarily responsible for protein synthesis in eukaryotic cells?

• Nucleus

• Ribosome

• Endoplasmic Reticulum

• Mitochondria

What is the significance of the stop codon in protein synthesis?

• Initiates translation process

• Indicates the end of protein synthesis

• Forms peptide bonds

• Releases the polypeptide chain
