Questions & Step-by-Step Solutions

What is the role of ribosomes in protein synthesis?
  • Step 1: Understand that ribosomes are small structures found in cells.
  • Step 2: Know that ribosomes are responsible for making proteins.
  • Step 3: Learn that proteins are made from smaller units called amino acids.
  • Step 4: Recognize that the instructions for making proteins come from a molecule called mRNA (messenger RNA).
  • Step 5: Realize that ribosomes read the mRNA sequence to know which amino acids to link together.
  • Step 6: Understand that as ribosomes read the mRNA, they join amino acids together to form a chain, creating a polypeptide.
  • Step 7: Finally, know that once the polypeptide is complete, it folds into a functional protein.
