The incorporation of a desired gene from specie to another is achieved using plasmids. We can also say it is used to incorporate a desired gene from particular specie to specie. It is also genetic modification.
The process by which the genetic makeup of an organism is altered is known as genetic modification or genetic engineering.
Examples in this case would be to take a plasmid into antibiotic-resistant bacteria and put it into bacteria that are not resistant to antibiotic, for that reason plasmid insertion into the bacteria that are not resistant to antibiotic would make it to be resistant to antibiotic.
Plasmids are a small molecule of DNA within a cell physically separated from a chromosomal DNA and is able to replicate independently. Plasmids are mostly found in bacteria as small circular, double-stranded DNA, though they are also presents in archaea and eukaryotic organisms.
Plasmids typically can be found in bacterial cells and the gene they carried has advantage towards bacteria (antibiotic resistance). Plasmids are wide in lengths, from about 1000 base pairs to hundred thousands of base pairs.
Plasmids are commonly used by scientists as tools to clone and manipulate genes. Plasmids that are used for these particular purposes are called vectors.
