are found in both prokaryotic and eukaryotic cells and are the sites of polypeptide synthesis.

Answer 1

Ribosomes are the sites of protein synthesis found in both prokaryotic and eukaryotic cells.

Step-by-step explanation:

Ribosomes are the cellular structures responsible for protein synthesis in both prokaryotic and eukaryotic cells. They are constructed from proteins and ribosomal RNA (rRNA) and are found in the cytoplasm. Prokaryotic ribosomes are called 70S, while eukaryotic ribosomes are 80S.
