Bacteria reproduce very fast that, a colony of bacteria will double in just half an hour. Hence they can perform many duties on the earth like scavenging the dead and waste. In fermenting the molasses and rapid yield in biotechnology etc. They can reproduce in many ways yet maintain genetic diversity and robustness. Unlike a eukaryotic cell, which does posses a nucleus, a bacteria does not undergo mitosis during replication, where the nucleus splits and DNA is distributed into two identical sets. Instead, bacteria reproduce by binary fission, a replication process that copies the bacteria's DNA and splits a single cell into two identical daughter cells. Transfer of genetic material occurs during the process of bacterial conjugation. During this process, DNA plasmid is transferred from one bacterium (the donor) of a mating pair into another (the recipient) via a pilus. The transfer can take about 90–150 minutes, and can be observed directly by video-enhanced microscopy [45] (Fig. 2.23). Episome type of bacteria are positive in transfering genetic material(DNA) from donor to the recipient during conjugation. This in terms of genetics is called genetic recombination. This is the most simple and early method of sexual reproduction. The recipient bacteria when reproduce by binary fission, produces new strain of bacteria which have the characters of both donor and recipient ... 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 : This is a physiological process by which the genetic mater transferred from one individual bacteria to the other during sexual reproduction.In case of bacteria, there is no sexual dimorphism. They are recognized as F + male or donor strain and F-or female or recipient strain. The F factor is also calk fertility factor or sex factor and is represented by an extra nuclear circular DNA present only in male. But as it is lacking in female, they are called F A mating bridge is a connection between two bacterial cells that provides a passageway for DNA in bacterial conjugation. A mating bridge is different from a sex pilus, which is a structure made by an F+ strain bacterium in bacterial conjugation Sex pilus acts as an attachment site that promotes the binding of bacteria to each other. Conjugation. How Do Bacteria Reproduce? As we have already discussed, bacteria reproduce through both asexual and sexual means. IN this section we will learn about these different modes of reproduction in bacteria. Asexual Reproduction in Bacteria. Binary Fission: In binary fission, a single bacterial cell divides into two daughter cells. At first, the bacterial cell reaches critical mass in its form and cell components. The circular double-stranded DNA of the bacteria undergoes replication ... Do bacteria reproduce during conjugation? No. How could E. coli acquire the Shiga toxin gene? Transduction, transformation, and conjugation are all possible. Why are R factors important in the treatment of infectious diseases? R factors carry antibiotic-resistance genes. Why are transposons sometimes referred to as "jumping genes"? They insert and excise from DNA randomly. Flow of Genetic ... Bacteria are prokaryotic organisms that reproduce asexually. Bacterial reproduction most commonly occurs by a kind of cell division called binary fission. Binary fission involves the division of a single cell, which results in the formation of two cells that are genetically identical. In order to grasp the process of binary fission, it is helpful to understand bacterial cell structure.
