Summary Introduction
To compare: The number and structure of chromosomes in prokaryotes and eukaryotes.
Introduction: Prokaryotes and eukaryotes are the basic cell types of all living cells. The prokaryotes are unicellular organisms that lack membrane-bounded nucleus and organelles. The eukaryotes possess a distinct nucleus that contains the genetic material of the cell.
