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

Intro to Biotechnology Mark Muller March 19, 2015 Chelsea Claverie Midterm Study Guide The Northern Blot detects the presence of certain RNA sequences, while the Southern blot can detect various DNA segments. Northern blot uses a gel electrophoresis, blot, RNA probes, and x-ray to determine the presence of a particular mRNA sequence that was immobilized and run in the electrophoresis. 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.

Chapter: 17 Viruses Overview: A Borrowed Life ? A virus is an infectious particle consisting of little more than genes packaged into a protein coat ? Viruses lead ?a kind of borrowed life?, existing in a shady area between life-forms and chemicals. ? Viruses called bacteriophages can infect and set in motion a genetic takeover of bacteria, such as Escherichia coli. ? A virus consists of a nucleic acid surrounded by a protein coat. ? Virus lack the metabolic machinery found in a cell, thus they can?t reproduce or carry out metabolism. Concept 17.1 A virus consist of a nucleic acid surrounded by a protein coat ? Virus smaller than a ribosome and even the largest virus is barely visible under light Microscope ? Some viruses can be crystalized

Chapter 18: Genetics of Viruses and Bacteria Concept 18.2 is not required knowledge for the AP Exam and has been intentionally omitted. Overview: Microbial Model Systems viruses called bacteriophages can infect and set in motion a genetic takeover of bacteria E. coli and its viruses are called model systems because of their frequent use by researches in studies that reveal broad biological principles beyond their value as model systems, viruses and bacteria have unique genetic mechanisms that are interesting in their own right bacteria are prokaryotes with cells much smaller and more simply organized than those of eukaryotes viruses are smaller and simpler still Concept 18.1: A virus has a genome but can reproduce only within a host cell
