Final answer:
Ribosomes in both eukaryotes and prokaryotes function as the sites of protein synthesis, despite differences in size, structure, and composition. Both types of cells rely on ribosomes to translate mRNA into proteins per genetic instructions.
Step-by-step explanation:
Ribosomes in eukaryotes and prokaryotes differ in many ways, but their fundamental function is consistent across both domains. The question asks in which way do ribosomes in eukaryotes and prokaryotes NOT differ. Considering all the options, the correct answer is c. Function. Both prokaryotic ribosomes (70S) and eukaryotic ribosomes (80S) serve as the sites of protein synthesis, despite differences in size, structure, and the specific RNA and proteins that make up their subunits. Eukaryotic ribosomes are made up of a 40S small subunit and a 60S large subunit, while prokaryotic ones consist of a 30S small subunit and a 50S large subunit. In both eukaryotes and prokaryotes, ribosomes play a crucial role in translating mRNA into polypeptide chains, essentially building proteins based on genetic instructions.
While eukaryotic cells may also have ribosomes within organelles like mitochondria and chloroplasts that more closely resemble those of prokaryotes, the core function of facilitating protein synthesis remains the same.
