• an amino acid chain is created

Where does translation occur?

• in the ribosome

• in the mitochondria

• in the nucleus

• in the chloroplast

What is the role of mRNA during protein synthesis?

• it carries the amino acids to where the protein chain is made

• it carries the instructions from the DNA to where the protein chain is made

• it puts the amino acids together forming the protein

• it adds complementary base pairs to the DNA, creating a mRNA strand
