Chromatin structure - Study guides, Class notes & Summaries

Eukaryote correct answersAn 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 correct answersThis shows as pale areas in the nucleas under electro magnification. It is a less densly packed form of chromati...

1. Describe common structural and functional features of eukaryotic cell. A. 1. Though mammals contain many types of cells which differ in function, shape, size etc., they have common features. 2. All types of cells contain nucleus, membrane and sub cellular components etc. 3. Each cell component has uniqe structure and function. Nucleus 1. It is located in the centre of most of the cells. It is surrounded by double layered membrane in which pores are present. 2. Pores present in...
