Prokaryotic and eukaryotic cells have in common:
- Ribosomes, which are cellular structures responsible for protein synthesis.
- Ribosomes are involved in translating genetic information from mRNA to synthesize proteins.
- Both prokaryotic and eukaryotic cells have ribosomes, although there are slight differences in size and location.
- Prokaryotic ribosomes are smaller (around 70S) and can be found floating freely in the cytoplasm or attached to the cell membrane.
- Eukaryotic ribosomes are larger (around 80S) and can be found both in the cytoplasm (free ribosomes) and on the rough endoplasmic reticulum (membrane-bound ribosomes).
- Despite these differences, ribosomes are essential for protein synthesis in both types of cells.
Summary
ribosomes are a common feature of both prokaryotic and eukaryotic cells, and they play a crucial role in protein synthesis.
