Here's a breakdown of how it works:
* Ribosomes read the genetic code: Ribosomes bind to messenger RNA (mRNA) molecules, which carry the genetic instructions for building proteins.
* Ribosomes assemble amino acids: Ribosomes move along the mRNA, reading the code three "letters" at a time (codons). Each codon corresponds to a specific amino acid.
* Ribosomes link amino acids together: The ribosome recruits transfer RNA (tRNA) molecules, each carrying a specific amino acid. The ribosome links these amino acids together in the order dictated by the mRNA, forming a polypeptide chain.
* Polypeptide chain folds into a protein: Once the polypeptide chain is complete, it detaches from the ribosome and folds into its unique three-dimensional shape, forming a functional protein.
So, ribosomes act like protein factories, using the instructions encoded in mRNA to assemble amino acids into functional proteins.
