Bacterial recombination is a type of genetic recombination in bacteria characterized by DNA transfer from one organism called donor to another organism as recipient. This process occurs in three main ways: Transformation, the uptake of exogenous DNA from the surrounding environment. Transduction, the virus-mediated transfer of DNA between bacteria.
Transduction This is an illustration of the difference between generalized transduction, which is the process of transferring any bacterial gene to a second bacterium through a bacteriophage and specialized transduction, which is the process of moving restricted bacterial genes to a recipient bacterium. While generalized transduction can occur ...
Bacteria regularly undergo genetic recombination in three main ways: Transformation, the uptake of exogenous DNA from the surrounding environment. Transduction, the virus-mediated transfer of DNA between bacteria. Conjugation, the transfer of DNA from one bacterium to another via cell-to-cell contact. [2] [3] [4] [5]
In the bacteria, oxidative phosphorylation in Escherichia coli is understood in most detail, while archaeal systems are at present poorly understood. [58] The main difference between eukaryotic and prokaryotic oxidative phosphorylation is that bacteria and archaea use many different substances to donate or accept electrons.
In this image, a gene from one bacterial cell is moved to another bacterial cell. This process of the second bacterial cell taking up new genetic material is called transformation. In molecular biology and genetics , transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic ...
A phylloquinone, sometimes called vitamin K 1, [16] is the next early electron acceptor in PSI. It oxidizes A 1 in order to receive the electron and in turn is re-oxidized by F x, from which the electron is passed to F b and F a. [16] [17] The reduction of F x appears to be the rate-limiting step. [15]
The electron transfers from pheophytin to plastoquinone (PQ), which takes 2e-(in two steps) from pheophytin, and two H + Ions from the stroma to form PQH 2. This plastoquinol is later oxidized back to PQ, releasing the 2e - to the cytochrome b 6 f complex and the two H + ions into the thylakoid lumen .
