Plasmid is the property of prokaryotic cell i.e. of bacteria generally no mamalian cell have plasmid but ya there can be chances to have lillte part of DNA sequence to be simillar that of plasmid DNA sequence in prokaryotes
Never. Only bacteria may have plasmids. Plasmids are circular pieces of DNA that carry genes for extra functions, usually beneficial to the bacteria like antibiotic resistance.
No they don't... only bacteria
No. Plasmids only exist in plant cells.
1. Scientists remove plasmids, small rings of DNA, from bacterial cells. 2. An enzyme cuts open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome. 3. The human insulin gene attaches the open ends of the plasmid to form a closed ring. 4. Some bacterial cells take up the plasmids that have the insulin gene. 5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.
Orginal Plasmids are extra chromosomal genetic material present in eukaryotes and some prokaryotes.Recombinant plasmids contain a gene of intrest ie,individual gene carrying a specific function can be inserted in to a specific site on original plasmid in cell culture via transformation.So the recombinant plasmid contain both gene of intrest and native genes.
F Plasmid
Yes, it donates a plasmid to the F negative cell where that plasmid reproduces and makes it own strand in the F negative cell.
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. ... Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid. This plasmid can be introduced into a bacterium by way of the process called transformation.

If you do not give antibiotics, the plasmid may lost after a few generation. it is because bacteria thinks that the extra DNA (plasmid) is not needed as the antibiotic is not present. That is the reason for keeping the culture always in antibiotic selection pressure.

red blood cell is the only human cell that does not contain a nucleus
A bacterial cell that has taken up plasmid DNA is transformed.

Plasmids have many different functions. They may contain genes that enhance the survival of an organism, either by killing other organisms or by defending the host cell by producing toxins. Some plasmids facilitate the process of replication in bacteria.
