What is donor in semiconductor?
In physics of semiconductors, a donor is a dopant atom (impurity) that, when added to a semiconductor, can form a n-type semiconductor. The process of adding controlled impurities to a semiconductor is known as semiconductor doping. This process changes an intrinsic semiconductor to an extrinsic semiconductor.
What is donor chemistry?
An electron donor is a chemical entity that donates electrons to another compound. It is a reducing agent that, by virtue of its donating electrons, is itself oxidized in the process. Typical reducing agents undergo permanent chemical alteration through covalent or ionic reaction chemistry.
What is donor organism?
The organism under study, which will be used to donate DNA for the analysis, is called the donor organism.
What is Transformation gene transfer?
Bacterial transformation is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment. The process of gene transfer by transformation does not require a living donor cell but only requires the presence of persistent DNA in the environment.
What does donator mean?

How are genes transferred from one chromosome to another?
The genes that get transferred (donor genes) depend on where the phage genome is located on the chromosome. Specialized transduction occurs when the prophage excises imprecisely from the chromosome so that bacterial genes lying adjacent to the prophage are included in the excised DNA.
When do genes get transferred in specialized transduction?
Specialized transduction. The genes that get transferred (donor genes) depend on where the phage genome is located on the chromosome. Specialized transduction occurs when the prophage excises imprecisely from the chromosome so that bacterial genes lying adjacent to the prophage are included in the excised DNA.
