Which statement about ribosomes is correct?

The Size of Prokaryotic and Eukaryotic Ribosomes

Ribosomes are cellular organelles responsible for protein synthesis. They can be found in both prokaryotic and eukaryotic cells, but there is a difference in size between the ribosomes of these two types of cells.

Prokaryotic ribosomes are smaller than eukaryotic ribosomes. Prokaryotic ribosomes are composed of a small 30S and a large 50S subunit, totaling 70S in size. On the other hand, eukaryotic ribosomes consist of a small 40S and a large 60S subunit, totaling 80S in size. This indicates that eukaryotic ribosomes are larger compared to prokaryotic ribosomes.

The size difference between prokaryotic and eukaryotic ribosomes is crucial in understanding the differences in protein synthesis between these two types of cells. Eukaryotic cells have a more complex internal structure than prokaryotic cells, and their larger ribosomes play a role in this complexity.
