A Tour of the Cell Overview: The Importance of Cells • All organisms are made of cells. o Many organisms are single-celled. o Even in multicellular organisms‚ the cell is the basic unit of structure and function. • The cell is the simplest collection of matter that can live. • All cells are related by their descent from earlier cells. Concept 2 Eukaryotic cells have internal membranes that compartmentalize their functions Prokaryotic and eukaryotic cells

Module 04 Homework Assignment Use the information presented in this module along with additional outside research to answer the questions: 1 Discuss the two methods of viral replication. The two methods of viral replication are done in animal viruses. The first method deals with DNA viruses and the second is RNA viruses. In the DNA virus‚ the viral DNA enters the nucleus of the host cell. Than it is transcribed into mRNA and leaves the nucleus into the cytoplasm. The early mRNA then translates
