What is the Difference Between Prokaryotic and Eukaryotic Genome?

The main differences between prokaryotic and eukaryotic genomes are as follows:

1. Structure: Prokaryotic genomes are mostly single, circular chromosomes, while eukaryotic genomes consist of one or two sets of linear chromosomes confined to the nucleus.
2. Location: Prokaryotic DNA is found in a coiled loop floating in the cytoplasm, whereas eukaryotic DNA is found inside the nucleus.
3. Size: Prokaryotic DNA is smaller and circular, while eukaryotic DNA is larger and linear.
4. Repetitive DNA: Prokaryotic genomes are compact and contain repetitive DNA without any introns, whereas eukaryotic genomes have a large amount of repetitive DNA and introns.
5. Introns: Prokaryotic DNA does not have introns, as they have transcription coupled with translation. In contrast, eukaryotic DNA contains introns.
6. Protein Binding: Prokaryotic DNA is naked and not surrounded by proteins, while eukaryotic DNA is bound to histone proteins.

In summary, prokaryotic genomes are smaller, circular, and found in the cytoplasm, while eukaryotic genomes are larger, linear, and found in the nucleus. Prokaryotic DNA is compact and has no introns, whereas eukaryotic DNA contains introns and is bound to histone proteins.
