* Decoding mRNA: Ribosomes read the genetic code from messenger RNA (mRNA) molecules. This code instructs the ribosome to assemble specific amino acids in a particular order.
* Amino Acid Assembly: Ribosomes bind to transfer RNA (tRNA) molecules, each carrying a specific amino acid. They then use the mRNA code to connect these amino acids together, forming a polypeptide chain.
* Protein Formation: The polypeptide chain folds into a complex three-dimensional structure, becoming a functional protein.
Think of it like this:
* mRNA: The blueprint for building the protein.
* Ribosome: The construction crew that follows the blueprint.
* tRNA: The delivery trucks carrying the building materials (amino acids).
* Protein: The finished building.
Therefore, ribosomes are the machinery that translates genetic information into functional proteins, making them the factories of the cell.
