What role do ribosomes play in protein synthesis?

  1. Breaking down proteins

  2. Production of mRNA

  3. Binding the amino acids together

  4. Translating mRNA into amino acids

The correct answer is: Translating mRNA into amino acids

Ribosomes play a crucial role in protein synthesis by translating mRNA into amino acids. Option A is incorrect because ribosomes do not break down proteins, they create them. Option B is incorrect because ribosomes produce proteins, not mRNA. Option C is incorrect because ribosomes do't bind amino acids together, they link them together using the mRNA code.
