Conjugation a simple form of sexual reproduction in some bacteria one bacterium transfers all or part of its genetic material to another through a bridge like structure called a pilus Reverse transcriptase conjugation. In bacteria, the direct transfer of DNA between two cells that are temporarily joined. donor has. a plasmid called F factor,transferred to recipient. Hfr strains. undergo recombination at high frequency, results from integration of F factor into bacterial chromosome. transduction. Bacterial Conjugation Definition Bacterial conjugation is a way by which a bacterial cell transfers genetic material to another bacterial cell. The genetic material that is transferred through bacterial conjugation is a small plasmid , known as F-plasmid (F for fertility factor), that carries genetic information different from that which is already present in the chromosomes of the bacterial cell. Conjugation [edit | edit source] Bacterial conjugation is the temporary direct contact between two bacterial cells leading to an exchange of genetic material (DNA). This exchange is unidirectional, i.e. one bacterial cell is the donor of DNA and the other is the recipient. Conjugation occur by physical contact between cells. The cell which transfer plasmid is called donor and the cell which receive the plasmid is called recipient. The cell which has received the plasmid from the donor cell is called trans-conjugant. The phenomenon of conjugation in bacteria was discovered by laderburg and Tatum in 1946. Conjugation, in biology, sexual process in which two lower organisms of the same species, such as bacteria, protozoans, and some algae and fungi, exchange nuclear material during a temporary union (e.g., ciliated protozoans), completely transfer one organism’s contents to the other organism (bacteria and some algae), or fuse together to form one organism (most bacteria and fungi and some algae). Within a given population of organisms, the various forms that may engage in conjugation are Conjugation is defined as the transfer of DNA in a site- and strand-specific manner from a donor to a recipient cell, which have formed close contacts with one another, that is, a mating pair.

Conjugation is the transfer of a plasmid or other self-transmissible DNA element and sometimes chromosomal DNA from a donor cell to a recipient cell via direct contact usually mediated by a conjugation pilus or sex pilus. Recipients of the DNA transferred by conjugation are called transconjugants. Define conjugation: the definition of conjugation is the changing of a verb’s form to show voice, mood, number, tense, and person. In summary, conjugation: is the form a verb takes to express action. varies by person, number, tense, aspect, or gender. includes regular and irregular verbs.
