Here's a breakdown:

* Ribosomes are complex molecular machines found in all living cells. They are responsible for translating the genetic code carried by messenger RNA (mRNA) into a chain of amino acids, which then folds into a functional protein.

* mRNA is a copy of a gene from the DNA in the cell's nucleus.

* Amino acids are the building blocks of proteins.

The ribosome moves along the mRNA molecule, reading the genetic code and linking together the correct amino acids in the order specified by the code. This process is known as translation.
