The differences between Prokaryotic and Eukaryotic cells

The differences between Prokaryotic and Eukaryotic cells

Prokaryotic cell is much smaller than Eukaryotic cell.

Eukaryotic cell-, where eu means true (true), karyon means nuclear, that is a complete nuclear envelope as the boundary of the nucleus

Prokaryotic cells -, where pro means before (before), which evolved before the complete nucleus. Its nucleus is not complete, that no nuclear membrane as the cytoplasm and the nucleus of the sub-boundaries.

Eukaryotic cells have a true nucleus but Prokaryotic cells have no nucleus.

DNA of prokaryotic cells with little protein but the organization of eukaryotic cells whose DNA contains a lot of complex structure of protein and both are used for the synthesis of ribosomal proteins are not the same size and composition.

Prokaryotic cells have a single strand of DNA, Eukaryotic cells are double-stranded DNA. Some of prokaryotic cells genetic information stored in the RNA, the genetic information of eukaryotic cells all stored in the DNA.
