Is human cell contain plasmid?
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
What type of gene is used to distinguish bacteria that carry a plasmid containing foreign DNA from those that don' t?
The plasmid that contains foreign DNA is engineered to also carry an antibiotic resistance gene. This antibiotic resistance gene codes for a protein that is able to inactivate an antibiotic thus keeping the cell alive. In the absence of the antibiotic resistance gene, the cells would not survive when exposed to an antibiotic. After transfection (the process of inserting the plasmid carrying the foreign gene into cells), the cells are gown in media containing an antibiotic. Cells that contain the plasmid (and therefore contain the antibiotic resistance gene) are able to survive in this medium. Cells that do not contain the plasmid (and therefore lack the antibiotic resistance gene) do not survive in this medium. The process described above is called selection
What are plasmid libraries?
A plasmid is a piece of circular DNA. These plasmids are transformed into bacteria/yeast. A library is made by taking pieces of DNA (from a genomic DNA digest, or cDNA) and inserting them into plasmids. The plasmids are then transformed into the organism and stored. Libraries are used to screen for new functional genes, usually when looking at new substrates or products that the yeast/bacteria can't make without the plasmid.
What is the rule of plasmid in biotechnology?
Plasmids are double stranded DNA molecules that serve as vector to carry a foreign gene in to the host.
What is a cloning vector?
The original plasmid defined as a DNA molecule that can carry foreign DNA into a host cell and replicate there.
A gene that makes it possible to distinguish bacteria that carry the plasmid from those that dont?
Genetic marker.
How are plasmids helpful to a bacterium?
It is thought that in bacteria a plasmid can be used as a defense mechanism for fighting viruses. When the virus inserts itself to the bacteria, the bacteria can use its enzymes to disconnect the plasmid and carry the viral nucleic acid with it.

A gene that makes it possible to distinguish bacteria that carry a plasmid from those that dont is called?
tha gene is hard so it sticks its BBC (big black cock) rite into tha bacteria's CAMEL TOE (big vigina) until she get soakin WET THE END
Can a bacteraial plasmid replicate independently of the bacterial chromosome?
Bacteria carry plasmids which is a double stranded DNA . It is how their extra chromosomal DNA is stored, they also have chromosomal DNA.Plasmids are extra-chromosomal DNA in Bacterial cells that replicate independently in cell. Plasmids are ubiquitous- means significant number of bacteria have plasmid and can have more that one plasmids. But Plasmids do not occur in all bacterial isolates.

yes flies are pathogens they carry bacteria

What bacteria do house flies carry?
The usually carry over 100,000 bacteria on its back alone

What percentage of food handlers carry dangerous bacteria?
50% of healthy food handlers carry dangerous bacteria.
