Answer:
The ribosome's function is to make polypeptides, which form proteins.
Step-by-step explanation:
Ribosomes are complex molecular machines found within all living cells that play a critical role in the synthesis of proteins. They are composed of two subunits, one large and one small, which work together to read the information stored in messenger RNA (mRNA) and use it to build a chain of amino acids, which are the building blocks of proteins. This process is known as translation and occurs in the cytoplasm of the cell. The ribosome's function is, therefore, to make polypeptides, which ultimately form proteins.
