SimBio: Mitosis Explored Questions and Answers 100% Pass Mitosis is the sequence of events that splits ___________ cells in to two genetically equivalent cells eukaryotic cells Eukaryotic Cells A cell containing structures enclosed in membranes. Prokaryotic Cells lack a cell nucleus or any other membrane-bound cellular component. They are primarily unicellular organisms such as bacteria. Nuclear Envelope The membrane that encloses genetic material (DNA) in a eukaryotic cell. This membrane se...

Eukaryote - Ans An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin - Ans This shows as pale areas in the nucleas under electro magnification. It is a less densly packed form of chromatin; 10% is even l...
