Here's a breakdown:
* Ribosomes: These are the protein-making machinery of the cell. They are found both in the cytoplasm (free-floating) and attached to the endoplasmic reticulum (ER).
* Genetic Code: The instructions for building a protein are encoded in DNA.
* Transcription: The DNA code is copied into a messenger RNA (mRNA) molecule.
* Translation: The mRNA molecule travels to a ribosome, where the code is read and translated into a specific sequence of amino acids.
* Amino Acids: These are the building blocks of proteins.
* Polypeptide Chain: The ribosome links amino acids together, forming a chain called a polypeptide.
* Protein Folding: The polypeptide chain then folds into a complex 3D structure, becoming a functional protein.
So, while the information for building a protein comes from DNA, it's the ribosomes that actually assemble the protein molecules.
