Prokaryotic and eukaryotic cells are very different in how they organize and manage their genetic material, which is what carries their genetic information.

1. Genetic Material Structure:

   • Prokaryotic Cells: These cells have one single, circular piece of DNA. It’s usually between 1,000 to 4,000 kb long and is found in an area called the nucleoid. Prokaryotic cells do not have a nucleus, so their DNA just floats around in the cytoplasm, the thick fluid inside the cell.
   • Eukaryotic Cells: In these cells, the DNA is organized into many pieces called chromosomes. Most eukaryotes have between 10 to 50 chromosomes. Their DNA is protected inside a membrane-bound nucleus, which keeps it separate from the rest of the cell.

2. DNA Packaging:

   • Prokaryotes: Their DNA is simpler and doesn't have as many proteins attached to it. Prokaryotic cells usually have fewer than 1,500 genes.
   • Eukaryotes: In these cells, DNA is wound around special proteins called histones. This makes a substance called chromatin. Eukaryotic cells can have more than 20,000 genes on average.

3. Replication and Transcription:

   • Prokaryotic Cells: These cells can copy their DNA (replication) right in the cytoplasm. They can also make proteins (translation) at the same time they are copying their DNA (transcription).
   • Eukaryotic Cells: Here, DNA replication happens inside the nucleus. The process of making messenger RNA (transcription) happens separately from making proteins (translation).

These differences show that eukaryotic cells are more complex and adaptable compared to prokaryotic cells.
