08-03 Translation

Which amino acid will be added to a protein chain if the mRNA codon is UAA?

At which organelle does translation take place?

Where are codons used in translation located?

• tRNA

• DNA

• mRNA

• rRNA

What are the three base segments of tRNA called?

What process is #2 and where is it located?

• transcription, nucleus
• translation, nucleus
• transcription, ribosomes
• translation, ribosomes

Identify the amino acid that belongs to the DNA sequence CCC.

What does a tRNA molecule carry?

• Proteins
• Amino Acids
• Nucleic Acids
• Carbohydrates

Which of the following is the LAST step of TRANSLATION?

• when “stop” codon is reached, ribosome releases completed protein

• mRNA attaches to the ribosome

• tRNA picks up and drops off amino acids at the ribosome

• ribsome reads mRNA codons
