* Ribosomes: These are small, complex structures made of RNA and protein. They act as the "protein factories" of the cell.

* DNA: Contains the genetic code that dictates the sequence of amino acids in a protein.

* Transcription: The DNA code is copied into messenger RNA (mRNA).

* Translation: The mRNA travels to the ribosome, where it is read and used to assemble amino acids into a protein chain.

Where are ribosomes found?

* Cytoplasm: Ribosomes are found free-floating in the cytoplasm, the gel-like substance that fills the cell.

* Endoplasmic Reticulum (ER): Some ribosomes are attached to the ER, a network of membranes throughout the cytoplasm. These ribosomes produce proteins that are destined for secretion from the cell or for use in other organelles.

So, while the information for protein production originates in the DNA, the actual assembly process takes place on the ribosomes.
