Which nucleic acid brings amino acids into the ribosomes from the cytoplasm?

• DNA

• mRNA

• rRNA

• tRNA

Which nucleic acid carries the message of the DNA's code from the nucleus to the ribosomes?

• DNA

• mRNA

• rRNA

• tRNA

What is the process of reading the mRNA's message and building a protein called?

• transcription

• translation

Where does translation take place?

• nucleus

• ribosomes

What is the process of writing the DNA's instructions onto a strand of mRNA called?

• transcription

• translation

Where does transcription take place?

• nucleus

• ribosomes

Put these steps in the correct order.

A - The mRNA travels to a ribosome and instructs tRNA to leave behind specific molecules.

B - The DNA has the instructions for making specific proteins.

C - rRNA binds the amino acids together to form a protein.

D - tRNA leaves behind its amino acid if the mRNA tells it to.

E - mRNA is made from the DNA's code.
