Introduction - What is Spintronics? Spintronics is Spin based electronics. The idea is to use the electron's spin, as well as it's charge. Electrons can spin in two directions (Spin-Up, Spin-Down, which is actually clockwise and anti-clockwise), and the spin is detectable as weak magnetic energy.
Viral Transduction. Transduction is the insertion of foreign DNA into a cell via a virus (See Reference 1 and 2). Viruses are made of a protein coat that houses DNA within. Viruses can bind to living cells and inject their DNA.Or, viruses can push into the host as a membrane-bound vesicle, before releasing their DNA inside the host. The use of recombinant DNA technology can insert foreign DNA into host cells that are then purposefully infected with viruses.ells have membranes that prevent DNA from simply diffusing in or out. This is the initial barrier that scientists must overcome in order to insert foreign DNA into a cell. The four ways of accomplishing this goal are transduction, transformation, transfection and injection.
Another way to introduce foreign DNA into bacteria is to transform or transduce them with the DNA and then allow them to mate. Bacterial mating is called conjugation, and occurs when two bacteria exchange DNA through a tube that connects them.hen the virus produces more of itself in the host cell, it also packages copies of the foreign DNA into the new viruses. When these new viruses burst out of the host cell, they are now carriers of the foreign DNA and can be used to introduce this DNA into other host cells.
