Answer the following question given this paragraph: 

The process of assembling amino acids into a protein takes place in the ribosome. This structure consists of two subunits, each of which is composed of both proteins and ribosomal RNA (rRNA). The two subunits clamp together on the mRNA and catalyze the formation of the amide linkages in the growing protein. When protein synthesis is complete, the two subunits dissociate and release the completed protein chain.


Q: Where does the process of assembling amino acids into a protein take place?

 Choices:

- in the nucleus

- in chromosomes

- in the chitin

- in the ribosome

A:
in the ribosome
