-This T4 head gets a tail and becomes a viral particle and is capable of infecting another bacterial cell. This excised phage DNA undergoes lytic cycle and infects another bacterium and transfers the bacterial genes from the donor bacterium. The most striking feature is the transfer of genetic material from cell to cell by viruses. Mutation as a source of variation. This set of Microbiology Multiple Choice Questions & Answers (MCQs) focuses on “Bacterial Transduction”. At times, a portion of the bacterial DNA remains attached to the detached phage DNA. What is homologous recombination? An introduction to genetic mutations. What are the key steps in the replication cycle (lytic infection) of… In this, only a few restricted bacteria are transferred from donor to recipient bacteria. So this transduction is called specialised. Transduction, transformation, conjugation, transposable elements. The virus enters the bacteria and integrates its genome within the host cell DNA. A. Specialised Transduction: In this process, the bacteriophage gets attached to a bacterial cell wall at the receptor site and the nucleic acid of bacteriophage is transferred into the cyto­plasm of … Explain. Impact of mutations on translation into amino acids. Email. It remains dormant and passes on from generation to generation. - New host cells infected by these viral particles received bacterial DNA instead of viral DNA. Transduction are of two types: A. Specialised transduction, and . Transduction is the process by which bacterial DNA is moved from one bacterium to another by a virus. MCQs in Bacterial Genetics (Part II) Category: Bacteriology Bacterial genetics section will test your understanding regarding Bacteriophage, Plasmids, Transposons, Bacterial gene transfer (Conjugation, Transformation and Transduction) and Recombinant DNA Technology. How much time is taken by the new DNA to make whole phage particles? Practice Questions Microbial Genetics ... _____ always results in the same few genes being transferred between bacteria. Here only the bacterial genes that are close to the site of prophage are transferred. Specialized Transduction. Question: Question (1 Point) Which Is The Right Statement On A Transduction Signal? B. Generalized transduction. The effects of mutations. Beatle and Tatum Watson and Crick Griffith This may occur in two main ways, recombination and headful packaging. Mutagens and carcinogens. generalized transduction specialized transduction transformation conjugatioin Who first observed conjugation? Mutations. instead of T4 genome, a piece of host cell's bacterial DNA is packaged in the phage head. Bacterial Transduction: Definition, Process & Advantages 7:53 Regulation of Gene Expression: Transcriptional Repression and Induction 8:17 In essence, this is the packaging of bacterial DNA into a viral envelope. This is carried out by temperate bacteriophage which undergoes the lysogenic cycle. It was first discovered by Joshua Lederberg in 1952. Questions Name the three types of bacterial exchange of DNA The donor bacterial cell in transfomation is probaly dead. a) 24 hours b) 60 mins c) 2 mins d) 10-20 mins View Answer What enzymes are involved with homologous recombination? 1. What are the two major enzymatic properties of E. Coli RecA protein? Generalized transduction is the process by which any bacterial gene may be transferred to another bacterium via a bacteriophage, and typically carries only bacterial DNA and no viral DNA.
