Document Summary
Introduction to the study of life and the scienti c method. What is a virus: viruses are acellular structures that require a living cell to reproduce (obligate parasites) Two main components to all viruses: capsid: outer portion comprised of proteins, nucleic acid core: dna or rna. Life and emergent properties: emergent property: a property that a complex system has but the individual members of the system do not. All aspects of life contain emergent properties. Viral life cycle: moves into cell, viral replication (attachment, entry (get into the cell, replication, biosynthesis, assembly, budding (can bud off from the cell and go off, repeat, video on blackboard - chapter 1 folder. Virus structure: whether or not the virus is alive or not is a gray area, are not homeostatic. Assembled from their parts and then released from the host cell: do not grow and develop. Best adapted viruses reproduce more than others. Mutations arise as virus particles are produced.
