The most striking feature is the transfer of genetic material from cell to cell by viruses. Transduction, transformation, conjugation, transposable elements. Bacteria can produce through both sexual and asexual means. It remains dormant and passes on from generation to generation. Bacteriophages are the group of viruses involved in transfer of genetic material from one bacterium to the other. Viruses that attack bacteria are called as bacteriophages. Transduction is the process by which bacterial DNA is moved from one bacterium to another by a virus. This is carried out by temperate bacteriophage which undergoes the lysogenic cycle. If you're seeing this message, it means we're having trouble loading external resources on our website. In this, only a few restricted bacteria are transferred from donor to recipient bacteria. In specialized transduction in bacterial cells, the phage also comes in contact with the bacterial host and injects its DNA into the bacteria. Sexual reproduction takes place through: Conjugation. The carrier phage is the transducer or vector. Transduction. Transduction, transformation, conjugation, transposable elements. Specialized Transduction. Through genetic recombination or exchange of genetic material, they introduce new characteristics in the new daughter cell. Let's review: Transduction is an important mechanism for horizontal gene transfer in bacteria. The virus enters the bacteria and integrates its genome within the host cell DNA. It may be general or specialised. Specialized Transduction. It was first discovered by Joshua Lederberg in 1952. Transformation. Gulp! Specialized transduction can occur only through the lysogenic cycle, i.e. Meaning of Transduction: The transfer of a small part of a bacterial genome from a donor to recipient bacterium through the agency of a bacteriophage is called transduction. Example of generalized transduction includes E.coli transduction by P1 phage. Such virus mediated gene transfer is termed as transduction. ADVERTISEMENTS: In this article we will discuss about the meaning and types of transduction of bacteria. Mechanisms that generate variation in prokaryote populations. Though bacteria don't exactly "eat" plasmids as depicted in this comic, when a bacterium uptakes a plasmid, the genes on the plasmid can give them different phenotypes. For example, this plasmid encodes a green fluorescent protein gene which makes the bacterium … Generalized transduction is used to study linkage information, gene mapping, comparing genomes of two different bacteria, mutagenesis, etc. In generalized transduction almost any […] However, unlike generalized transduction, the phage enters the lysogeny cycle rather than producing enzymes that can destroy the bacterial DNA. by temperate phage.
