Translation takes place in the 

• ribosome
• chloroplast
• nucleus
• mitochondria

Brings the amino acids to the ribosome

• mRNA
• tRNA
• rRNA
• DNA

What would be the tRNA anticodon for the mRNA codon CAG?

• GTC
• GUC
• CUG
• CAG

What is the term for a three-nucleotide sequence that codes for an amino acid?

• base
• codon
• amine
• serine

Which phrase best describes translation?

• converts mRNA into a polypeptide
• catalyzes bonds between amino acids
• produces RNA from DNA molecules
• recycles tRNA molecules for reuse

What type of bonds are forming during translation?

• Peptide bonds

• Acid bonds

EXTRA AWESOME QUESTION: Which types of cells can begin the process of translation even before the mRNA has been completely transcribed?  

• Eukaryotes
• Prokaryotes
• Both Prokaryotes and Eukaryotes can
• No cells can can do this

The job of tRNA is to

• carry amino acids to the ribisomes
• carry ribisomes to the ER
• carry glucose to mitochondria
• carry mRNA out of the nucleus
