Q: What is the role of ribosomes in protein synthesis?
Solution:
Ribosomes are the cellular machinery that translates mRNA into polypeptides, facilitating protein synthesis.
Steps: 7
Show Steps
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.
