The enzyme is conserved in eukaryotes and also found in some prokaryotes.

After all, before prokaryotes appeared there was no cellular life at all.

The key difference between prokaryotes and eukaryotes is the complexity of the cells.

Small RNA-guided protein complexes play an essential role in CRISPR-mediated immunity in prokaryotes.

That seems to fit with what we know about living prokaryotes.

However, it is widely held that prokaryotes are too small to sense spatial gradients.

Biological cells come in two main types: prokaryotes and eukaryotes.

Reversible phosphorylation is the key mechanism regulating several cellular events in prokaryotes and eukaryotes.

But the plants, animals and fungi we see and interact with are not prokaryotes.

Feo is the major ferrous iron transport system in prokaryotes.

CRISPR-Cas systems are RNA-guided immune systems that protect prokaryotes against viruses and other invaders.

Several multiprotein complexes assisting Fe-S assembly have been identified in both prokaryotes and eukaryotes.

Clustering of functionally related genes in operons allows for coregulated gene expression in prokaryotes.

Not least of them is the fact that prokaryotes don't seem to swallow cells today.

Though mitochondria are embedded in your cells, they are self-contained entities, very similar to prokaryotes.

It is well established that prokaryotes and eukaryotes alike utilize phosphotransfer to regulate cellular functions.
