The term plasmid was coined in 1952 by the American molecular biologist Joshua Lederberg to refer to "any extrachromosomal hereditary determinant." [14] [15] The term's early usage included any bacterial genetic material that exists extrachromosomally for at least part of its replication cycle, but because that description includes bacterial viruses, the notion of plasmid was refined over time ...
The pBR322 plasmid is one of the first plasmids widely used as a cloning vector. Plasmids with specially-constructed features are commonly used in laboratory for cloning purposes . These plasmid are generally non-conjugative but may have many more features, notably a " multiple cloning site " where multiple restriction enzyme cleavage sites ...
Cells harboring the plasmid will survive when exposed to the antibiotic, while those that have failed to take up plasmid sequences will die. When mammalian cells (e.g. human or mouse cells) are used, a similar strategy is used, except that the marker gene (in this case typically encoded as part of the kanMX cassette) confers resistance to the ...
An example of a plasmid cloning vector which modifies the inserted protein is pFUSE-Fc plasmid. In order to genetically engineer insulin, the first step is to cut the MCS in the plasmid being used. [8] Once the MCS is cut, the gene for human insulin can be added making the plasmid genetically modified.
Schematic representation of the pBR322 plasmid, one of the first plasmids widely used as a cloning vector. A cloning vector is a small piece of DNA that can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes. [ 1 ]
DNA transposons, LTR retrotransposons, SINEs, and LINEs make up a majority of the human genome. Mobile genetic elements (MGEs), sometimes called selfish genetic elements, [1] are a type of genetic material that can move around within a genome, or that can be transferred from one species or replicon to another. MGEs are found in all organisms.
[9] [10] In 1993, Jeffrey Ulmer and co-workers at Merck Research Laboratories demonstrated that direct injection of mice with plasmid DNA encoding a flu antigen protected the animals against subsequent experimental infection with influenza virus. [11] In 2016 a DNA vaccine for the Zika virus began testing in humans at the National Institutes of ...
Vectors used for E. coli expression can be used in this system although specifically designed vectors for this system are also available. Eukaryotic cell extracts may also be used in other cell-free systems, for example, the wheat germ cell-free expression systems. [41] Mammalian cell-free systems have also been produced. [42]
