Q: What are the differences between prokaryotic and eukaryotic cells?
To grasp the unique structure of prokaryotic cells, it's essential to begin with their basic composition. Unlike eukaryotic cells, which possess membrane-bound organelles and a membrane-enclosed nucleus, prokaryotes lack these distinct structures. Instead, their DNA is found in a single, circular chromosome or multiple smaller plasmids.
Prokaryotic cells lack membrane-bound organelles, have a smaller size range, and exhibit a significant difference in their DNA localization compared to eukaryotic cells.
Prokaryotic cells rely on a primitive ribosome, known as the 70S ribosome, composed of proteins and RNAs. These basic machines facilitate protein synthesis by translating messenger RNA (mRNA) into amino acid chains that perform various cellular functions. The absence of a eukaryotic cytoskeleton and endoplasmic reticulum means that prokaryotes employ an intricate network of nucleoid-associated proteins and DNA-binding proteins that provide structural support and organization to their nucleoids.
