Lesson 42: Protein Synthesis Translation

Select all answers below that participate in the process of translation.

• tRNA

• DNA

• ribosome

• Amino acids

If the mRNA codon is AAG, what is the tRNA anti-codon?

• TTG

• AAU

• GGU

• UUC

The _________________ is a sequence of three nucleotides on mRNA that signals the end of protein synthesis.

• ribosome

• stop codon

• protein

• anti-codon

The _____________ links amino acids together to form a protein.

• peptide bond

• anti-codon

• tRNA

• ribosome

Select all activities below that occur during translation.

• tRNA brings amino acids to the ribosome.

• Amino acids are added to a growing protein as anti-codons match up with mRNA codons.

• The newly created mRNA arrives at a ribosome in the cell.

• A stop codon signals completion and releases the protein.

Although there are a limited number of amino acids, a great variety of proteins are possible because -

• the same amino acid can transform itself.

• the size and configuration of amino acids can vary.

• the sequence and number of amino acids can vary.

• there is a greater number of mRNAs than tRNAs.

During translation, the actual construction occurs with the protein being made at the _______________.

If the mRNA codon is CCU, what amino acid will tRNA bring to the growing protein chain?

• Glycine

• Proline

• Serine

• Leucine
