Small, circular DNA molecules that can exist independently of the chromosome 2. Figure: competence in Bacillus subtilis. The cell solves the problem of packaging this enormous macromolecule by condensing and looping it into a supercoloid state. In transduction, phage carry bacterial chromosomal DNA from a cell that underwent a lytic infection to another bacterial cell. Transduction. Conjugation is carried out in several steps: 1. DNA replication, genetic characters, their changes & transfer to next generations. Bacteria are ideal for genetic research and engineering because they are easily cultured, possess single chromosomes with less complexity, and have plasmids that can be conveniently used as cloning vectors. Microbial Physiology is an intensive course with the goal of integrating biochemistry and Bacterial nucleoid The genetic information of bacterial cell is mostly contain in a single, long molecule of double-stranded deoxyribonucleic acid (DNA). Conjugation is the technique of transfer of genetic material from one bacteria to another placed in contact. Mating pair formation 2. Some Microbial and Genetics Resources, Websites 1. Individual bacteria were first observed microscopically by Antony van Leeuwenhoek at the end of the 17th century. There are various conjugal plasmids carried by various bacterial species. 0 Conjugal DNA synthesis 3. There are several ways to do this. A Short Course in Bacterial Genetics: Lab Manual, Cold Spring Harbor Laboratory Press. You are also requested to visit our Genetics PPT and Genetics MCQ pages. These three mechanisms are outlined in the figure below. Bacteria can acquire DNA (i.e., new genes) in 3 basic ways: 1) Transformation • uptake and retention of external DNA molecules 2) Conjugation • direct transfer of DNA from one bacterium to another 3) Transduction • the transfer of DNA between bacteria by a virus MICROBIAL GENETICS PREPARED BY WELFREDO YU,JR. This method was proposed by Lederberg and Tatum. Microbial Genetics Notes.

This process doesn’t require a living donor cell and only requires free DNA in the environment. Notes: 1) For the last lecture section (Activating Transcription), the exam questions will all come from the lecture notes. The course is taught by one instructor whom is faculty in the department of Biochemistry and Microbiology. Lectures and seminars will cover the following topics: • Evolutionary genetics: prebiotic chemistry; ribozymes as molecular fossils; molecular phylogenetics and population genetics. Lecture 13 Gene Manipulation in Bacteria There is no meiosis in bacteria so special techniques have been worked out for manipulating genes in bacteria so that mapping experiments, strain construction, and complementation tests can be done. Desire2Learn (D2L) Site Powerpoint presentations, copies of literature discussion and reference articles, and other materials will be available via the class D2L site (Microbial Genetics Bio-375/575). Bacteria are readily visible when present in large numbers because they make a … The bacterial … They discovered that the F-factor can move between E.colicells and proposed the concept of conjugation.

The protein involved in transformation of these Gram +ve bacteria is a product of com; In Bacillus subtilis, the com gene are organized into several operons. MICROBIAL GENETICS 1. PowerPoint lecture on Microbial Genetics used in an actual college microbiology classroom. In conjugation, bacteria transfer plasmid or chromosomal DNA to another bacterial cell through a bridge between the cells called a pilus. For the easy navigation, the topics were categorized into modules. • Molecular genetics: introduction to bacterial genetics; structure of the bacterial chromosome; comparative genomics; DNA replication and fidelity. This lecture note discusses the principles of genetics with application to the study of biological function at the level of molecules, cells, and multicellular organisms, including humans. Bacterial genetics is used as a model to understand . Genetics Lecture Notes by MIT. The textbook is still relevant, but only as a resource if there are topics in the slides that are unclear. About Science Prof Online. Bacterial Genome – DNA, usually circular, sometimes linear, 1500X the cell length Plasmid – extrachromosomal circular, double stranded DNA - much smaller than a genome, not found in all bacteria - usually transferred by … Micro 2054 - Microbial Genetics. Chapter 9- An Introduction to Microbial Genetics* *Lecture notes are to be used as a study guide only and do not represent the comprehensive information you will need to know for the exams. Overview: Microbial Model Systems. MICROBIOLOGY - AN INTRODUCTION, by Tortora, Funke, and Case, 10th edition. Description: Microbial physiology is a 3 credit course with two 1 hour 20 minute lectures each week. Viruses and bacteria are the simplest biological systems—microbial models in which scientists find life’s fundamental molecular mechanisms in their most basic, accessible forms. PowerPoint Resources. 1953 – James Watson, Francis Crick, and Maurice Wilkins discovered structure of DNA. Chapter 18 The Genetics of Viruses and Bacteria Lecture Outline . Characteristics a) Much smaller than the chromosome (<1/20th the size), ranging in size from 200 kb to 2 kb. Choose from 500 different sets of lecture notes microbial genetics flashcards on Quizlet. Microbial Physiology 11:680:481 . This results in genetically identical daughter cells. Bacteria reproduce by the process of Binary Fission: the chromosome in the mother cell is replicated and a copy is allocated to each of the daughter cells. Bacterial transformation is the transfer of free DNA released from a donor bacterium into the extracellular environment that results in assimilation and usually an expression of the newly acquired trait in a recipient bacterium.. Microorganisms have the ability to acquire genes and thereby undergo the process of recombination. 3. the lecture notes before coming to class.
