Ch 19: Viruses Overview: A Borrowed Life Viruses called bacteriophages can infect and set in motion a genetic takeover of bacteria, such as Escherichia coli Viruses lead ?a kind of borrowed life? between life-forms and chemicals The origins of molecular biology lie in early studies of viruses that infect bacteria Concept 19.1: A virus consists of a nucleic acid surrounded by a protein coat The Discovery of Viruses: Scientific Inquiry Tobacco mosaic disease stunts growth of tobacco plants and gives their leaves a mosaic coloration In the late 1800s, researchers hypothesized that a particle smaller than bacteria caused the disease In 1935, Wendell Stanley confirmed this hypothesis by crystallizing the infectious particle,now known as tobacco mosaic virus (TMV)

Intro to Biotechnology Mark Muller April 4, 2015 Chelsea Claverie Exam 3 Study Guide Southern blotting - Southern blot uses an autoradiograph in combination with an electrophoresis gel to identify similarities between DNA. Similar DNA should travel the same distance in the electrophoresis, on the blot, and have the same binding sites from probes on the autoradiograph. Retrovirus Life Cycle in Cells: Retrovirus originates in nucleus of cell, binds to cell receptor of new cell to infect, reverse transcripts, then binds to the host DNA

18.1: Viruses and Bacteria Viruses What is a Virus? Virus: composed of nucleic acids enclosed in a protein coat and are smaller than the smallest bacterium Biologists consider viruses to be nonliving because viruses are not cells. Viruses do not carry out respiration, grow or develop. Viruses can only multiply when they are inside a living cell. Host cell: cell in which a virus replicates Almost all viruses are parasites because they destroy the cells in which they multiply. Viruses can infect the organisms of all six kingdoms. Because viruses are not alive, scientists do not use binomial nomenclature to name them.

AP Biology ? Chapter 19 Viruses ? Overview: A Borrowed Life ? Viruses:???????? Basically just genes packaged in protein coats. ??????????????????????? They lack the structures and metabolic machinery found in cells ? ? Are viruses living or nonlinving? -??????????? They cannot reproduce or carry out metabolic activities outside of a host cell ? so they are kind of between living and non-living (hence ?A borrowed life?. ? ? A lot of what we know about molecular biology comes from the study of viruses ? a lot of the information about genes and nucleic acids. ? ??????????? The ability to manipulate genes and transfer them comes from the study of viruses ??????????? Viruses are used as the agents of gene transfer in gene therapy. ? ? ? ?
