    I think thats correct because... "The first eukaryotic cells (organisms with one or more complex cells, each of which contains a nucleus and is surrounded by a membrane that holds the cell’s genetic material) evolved sometime between 2.5 and 1.7 billion years ago, perhaps coincident with the rise in atmospheric oxygen to a level able to support this more complex life. The nucleus in these cells was able to hold and protect complex molecules such as RNA and DNA." http://www.physicsoftheuniverse.com/topics_life_early.html
