microbial genetics including transformation transduction conjugation ppt

DNA Replication & Mutation 4. Allows for Recombinant DNA Technology. Sometimes the virus accidentally packages some of the bacteria’s DNA in a phage (viral cell component) instead of its own DNA. 2 0 obj Transduction, transformation, conjugation, transposable elements. Transduction is the transfer of genetic information from a donor to a recipient by way of a bacteriophage. 3. In contrast, in sexually reproducing organisms, 2. A donor cell contains a F (fertility) plasmid making it F. A conjugation pilus (genes for which are on the F plasmid) forms and the donor cell transfers a copy of the F plasmid to the recipient. Genotypes within populations vary and this, 2. Transformation is a genetic transfer mechanism by which foreign genetic material is taken up by a cell. Bacterial Conjugation • Bacteria are haploid organisms with a single, circular chromosome. Flagella. 3. In this process the new genes are acquired directly from the environment. endobj In nature, this genetic material often comes from adjacent lysed bacteria and can include plasmid DNA or fragmented DNA released into the environment. endobj Scientists have discovered that it is possible to transfer DNA from one bacterial cell to another by another two mechanisms: transformation and transduction.

The most common mechanism for horizontal gene transmission among bacteria, especially from a donor bacterial species to different recipient species, is conjugation. Nov 26, 2015 - 8.4 Plasmids Circular genetic elements that reproduce autonomously and have an extra-chromosomal existence: KB in size Typical plasmid 1/20 of chromosome Most are circular double-stranded DNA, some linear ds DNA Transmitted from cell to cell via conjugation process Some can integrated into chromosome Can carry a variety of genes for production of toxin, resistance to … ScienceProfOnline.com.

Recombinant DNA technology 1. cloning of specific DNA fragments on plasmids and the transfer into bacteria via transformation and/or conjugation (Fig. GENETICS AND MOLECULAR BIOLOGY - Recombination - Transformation, Transduction and Conjugation - Yasuo Hotta ... sex chromosomes was reported in many other species, including some water plants. How is this variability passed on (heritable)? September 12, 2013 Acharya Tankeshwar Microbial Genetics 1. R. Lia K. Iswara, Dr, MS, SpMK Department of Microbiology FK USU. Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. At recombination rates gt 10-5 exchanges per, 3. How do we determine relationship between species? Mechanisms of bacterial horizontal gene transfer include transformation, transduction, and conjugation. endobj Bacterial genetics vs eukaryotic genetics - Eukaryotes use sexual reproduction : In many species, sex is essential to all reproductions. Even with relatively low levels of recombination, Genetic exchange can transfer adaptations, Adaptive mutations in bacteria have the potential. from the environment (such as DNA released from a dead organism). transformation transcription transduction RNA replication The process by which protein is made from an RNA template is called which of the following. Bacterial conjugation and transfer of F plasmid. Transformation. Replica Plating, pt. /XObject <> Bacterial genetics, lectures 3 ST •Replication -DNA •Regulation •Change - mutation ... •Conjugation, transduction, incorporation . Transformation and Transduction • Conjugative Transposons • These genetic elements share attributes with conjugal plasmids and transposons • A transposition event between two cells • Requires all the functions found in conjugation plus those of transposition. It is the subfield of genetics devoted to the study of bacteria. Transduction - injection of foreign DNA by a bacteriophage virus into the host bacterium Transfection. F. Griffith discovered the process of transformation in 1928. Do you have PowerPoint slides to share? Phage typing ... - Title: PowerPoint Presentation Author: Jerome Burg Last modified by: tempuser Created Date: 8/6/2010 6:35:02 PM Document presentation format: On-screen Show (4:3). Genetic recombinations in bacteria occur as the result of transformation, transduction, and conjugation. >> Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.
