Final answer:
Ribosomes are small organelles involved in protein synthesis. Some ribosomes are associated with the rough ER and are responsible for translating RNA into proteins.
Step-by-step explanation:
Ribosomes are small organelles that are responsible for protein synthesis in cells. They can be found in both prokaryotes and eukaryotes. In eukaryotic cells, some ribosomes are associated with the rough endoplasmic reticulum (ER) and are involved in the synthesis of proteins that are destined for the Golgi apparatus. These ribosomes are also responsible for translating RNA into proteins. Therefore, the statement in the question is true.
