Sexual reproduction takes place through: Conjugation. For example, this plasmid encodes a green fluorescent protein gene which makes the bacterium … Specialized transduction can occur only through the lysogenic cycle, i.e. It may be general or specialised. Transformation. Mechanisms that generate variation in prokaryote populations. by temperate phage. However, unlike generalized transduction, the phage enters the lysogeny cycle rather than producing enzymes that can destroy the bacterial DNA. Specialized Transduction. The most striking feature is the transfer of genetic material from cell to cell by viruses. Gulp! Generalized transduction is used to study linkage information, gene mapping, comparing genomes of two different bacteria, mutagenesis, etc. Transduction is the process by which bacterial DNA is moved from one bacterium to another by a virus. Transduction, transformation, conjugation, transposable elements. Transduction. The virus enters the bacteria and integrates its genome within the host cell DNA. If you're seeing this message, it means we're having trouble loading external resources on our website. In specialized transduction in bacterial cells, the phage also comes in contact with the bacterial host and injects its DNA into the bacteria. Viruses that attack bacteria are called as bacteriophages. Through genetic recombination or exchange of genetic material, they introduce new characteristics in the new daughter cell. Specialized Transduction. In this, only a few restricted bacteria are transferred from donor to recipient bacteria. In generalized transduction almost any […] It remains dormant and passes on from generation to generation. Such virus mediated gene transfer is termed as transduction. Transduction, transformation, conjugation, transposable elements. Example of generalized transduction includes E.coli transduction by P1 phage. Bacteriophages are the group of viruses involved in transfer of genetic material from one bacterium to the other. 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. Let's review: Transduction is an important mechanism for horizontal gene transfer in bacteria. Bacteria can produce through both sexual and asexual means. The carrier phage is the transducer or vector. ADVERTISEMENTS: In this article we will discuss about the meaning and types of transduction of bacteria. This is carried out by temperate bacteriophage which undergoes the lysogenic cycle. It was first discovered by Joshua Lederberg in 1952. 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.
