What is the function or purpose of mRNA?

• Carries amino acids to protein-building ribosomes

• Facilitates chemical reactions that form ribosomes

• Serves as the site of protein synthesis

• Carries genetic information from the DNA to ribosomes

What is the purpose of tRNA?

• Carries amino acids to protein-building ribosomes

• Serves as the site of protein synthesis

• Carries genetic information from the DNA to ribosomes

• Facilitates of the mRNA

Why are proteins essential to all life?

• They form cellular membranes

• They are used for energy storage

• They provide genetic information

• They build structure and carry out cell metabolism
