WebEukaryotes typically have much more DNA than prokaryotes: the human genome is roughly 3 billion base pairs while the E. coli genome is roughly 4 million. For this reason, eukaryotes employ a different type of packing strategy to fit their DNA inside the nucleus (Figure 4). At the most basic level, DNA is wrapped around proteins known as histones.

A sister of Gloeomargarita lithophora has been engulfed by an ancestor of the Archaeplastida, ... Over time, many genes from the chloroplast have been transferred to the nucleus of the host cell. Eukaryotic cells contain membrane-bound organelles such as the nucleus, the endoplasmic reticulum, and the Golgi apparatus. Eukaryotes may be either unicellular or multicellular. In comparison, prokaryotes are typically unicellular. Unicellular eukaryotes are sometimes called protists.
