Genetic Translation Quiz

What is the process called in which genetic information encoded in mRNA is translated into a sequence of amino acids?

• Transcription

• Translation

• Replication

• Mutation

What is the role of messenger RNA (mRNA) in translation?

• It binds to amino acids

• It transports genetic information to ribosomes

• It forms peptide bonds

• It acts as an enzyme

What do ribosomes read in triplets of bases during translation?

• Anticodons

• Amino acids

• Codons

• Peptide bonds

What binds to specific codons via complementary anticodons?

• Messenger RNA

• Ribosomes

• Transfer RNA

• Polypeptides

What is the function of the large subunit of the ribosome?

• It binds to mRNA

• It contains binding sites for tRNA

• It synthesizes mRNA

• It transports amino acids
