Interactive Video - Translation

What is the role of mRNA in the cell?

• It carries instructions from DNA to build proteins.

• It stores genetic information.

• It breaks down proteins.

• It transports oxygen in the blood.

What is the start codon for mRNA translation?

• UAA

• AUG

• GUA

• UCC

What is the function of tRNA during translation?

• It carries amino acids to the ribosome.

• It synthesizes DNA.

• It stores energy for the cell.

• It transports mRNA out of the nucleus.

What happens during the elongation step of translation?

• The ribosome binds to the mRNA.

• The ribosome assembles amino acids into a chain.

• The ribosome separates into two pieces.

• The ribosome releases the amino acid chain.

How did Dr. Katalin Karikó contribute to the development of mRNA vaccines?

• She invented the first ribosome.

• She discovered the structure of proteins.

• She discovered a molecule that helps mRNA escape the immune system.

• She developed the first DNA vaccine.
