Bacterial Conjugation Definition 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. Black Friday Sale! (2) A form of sexual reproduction in certain algae and fungi where a male gamete unites with a female gamete resulting in the union of their nuclei and the subsequent formation of a zygote. The forms may or may not resemble each other in size, shape, or motility. It is through this process that resistance to antibiotics can be transferred from one bacterial cell to another. Using the genomic shortcut to predict bacterial behavior. 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). Definition noun, plural: conjugations (biology) (1) The process whereby two ciliates come together in a temporary fusion to exchange micronuclear material, then separate, each being a fertilized cell. Any information here should not be considered absolutely correct, complete, and up-to-date.

They differ in some physiological or genetic characteristic and are distinguished by biologists through the use of symbols such as + and - or by letters of the alphabet if more than two forms occur. The process does not result in an increase in numbers but is a simple exchange of genetic material between two individual cells. way by which a bacterial cell transfers genetic material to another bacterial cell This takes place through a pilus. 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). It is a parasexual mode of reproduction in bacteria. The different types of plant tissues are m.. Meaning of Bacterial Conjugation Bacterial conjugation is a process, where a donor cell (having fertility factor) comes in close contact with the recipient cell by forming a protuberance called conjugation tube that passes on the genetic material from one cell to other.

(3) The temporary joining together of two bacterial cells to transfer genetic material via the plasmid (either as solitary or as part of a chromosome) from the donor cell to the recipient cell.
