Plasmid | DNA replication, genetic engineering, cloning | Britannica
Nov 28, 2024 · Plasmids are extremely valuable tools in the fields of molecular biology and genetics, specifically in the area of genetic engineering (q.v.). They play a critical role in such procedures as gene cloning, recombinant protein production (e.g., of human insulin), and gene therapy research.
Plasmid - Wikipedia
A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms.
Plasmids as Genetic Tools and Their Applications in Ecology and ...
Jun 19, 2019 · Plasmids are used in the techniques and research of genetic engineering and gene therapy by gene transfer to bacterial cells or to cells of superior organisms, whether other plants, animals, or other living organisms, to improve their resistance to diseases or to improve their growth rates or to improve any other required traits.
Plasmid - National Human Genome Research Institute
Dec 1, 2024 · A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organisms. Plasmids are physically separate from chromosomal DNA and replicate independently. They typically have a small number of genes — notably, some associated with antibiotic resistance — and can be passed from one cell to another.
Plasmid evolution: Current Biology - Cell Press
Oct 5, 2020 · Plasmids are genetic elements that colonize and replicate in prokaryotic cells (Box 1). They are considered a major driving force of prokaryote evolution, as they can migrate between populations, making them potent agents of lateral DNA transfer and microbial warfare.
How are Plasmids Used in Genetic Engineering - Pediaa.Com
Mar 5, 2018 · Plasmids are small circular DNA molecules mainly found in bacteria. They are extrachromosomal DNA elements, capable of replicating independently from the bacterial genome. The genes encoded in plasmids help bacteria to survive under stress conditions. Several to many copies of plasmids can naturally occur inside a bacterial cell.
