Gene Expression: Translation Review

Which of these is the purpose of translation?

• produce protein

• produce ribosomes

• produce tRNA

• produce genes

What process must occur before translation can happen?

• DNA is used to make mRNA during replication

• DNA is used to make mRNA during transcription

Which amino acid is made from the RNA codon UUA?

• Phenylalanine
• Leucine
• Serine
• Tyrosine

What structure in a cell is the site for making proteins?

• ribosomes
• mitochondria
• lysosome
• Golgi body

The diagram shows a step during translation. Which of the following steps would you predict would happen next?

• A tRNA carrying the mRNA will bind to the A site

• A tRNA carrying the next Amino Acid will bind to the mRNA at the A site

• A tRNA carrying the next Amino Acid will bind to the mRNA at the E site

• An mRNA will bind to the A site

The diagram shows another step in translation. What step will happen next

• the ribosome will break apart and translation will end

• another tRNA molecule will bind to the E site

• a bond will be formed between the Amino Acids of the tRNAs

• the ribosome will shift to the next mRNA codon and release the empty tRNA molecule

In this diagram of the translation process, what would happen if a stop codon appears at the A site?

• the ribosome stops and waits for another start codon

• the ribosome releases the completed protein and the empty tRNAs

Process in which amino acids are assembled into proteins at the ribosome?

• Translation
• Transcription
• Meiosis
• Replication

If the mRNA sequence is AGA UUU CGA GCC,
what is the complementary tRNA anticodons?

• AGA TTT CGA GCC
• UCU AAA GCU CGG
• TCT AAA GCT CGG
• UCU AAA CGA GGG

Brings the amino acids to the ribosome

• mRNA
• tRNA
• rRNA
• DNA
