Yes, drug resistance genes can be carried on plasmids, which are small, circular DNA molecules found in bacteria. Plasmids can be easily transferred between bacteria, spreading drug resistance within a population. This transfer of plasmids contributes to the development of antibiotic-resistant bacterial strains.
The plasmid have a "reporter gene" inside it, generally resistance to specific antibiotic. the plasmid is transformed into bacteria that don't have resistance to that specific antibiotic drug, and than the cultured on a petri-dish that contain the antibiotic drug. Only bacteria that had receive the plasmid will have resistance and grow, all the other will die.
The source of antibiotic resistance is often plasmids known as R plasmids, which carry genes that confer resistance to antibiotics. These plasmids can be transferred between bacteria, spreading antibiotic resistance throughout microbial populations.
A plasmid (conjugative plasmid) that has a resistance gene on it, can transfer itself to another bacterial cell (called conjugation) or assist in the transfer of a non-conjugative plasmid that has a resistance gene to another cell (called mobilization). Whichever way it happens, once the plasmid is transfered to the new cell, this cell too may show signs of resistance to the particular antibiotic. This is one of the ways of the speard of resistance amongst bacteria
An extra loop of DNA that carries antibiotic resistance genes is called a plasmid. These genes can provide bacteria with the ability to survive exposure to antibiotics.
False. Cells containing a plasmid with an antibiotic resistance gene will survive in the presence of the antibiotic because they can produce the protein that confers resistance, allowing them to withstand the antibiotic's effects.

Plasmid curing is the process of obviating the plasmid encoded functions such as antibiotic resistance, virulence, degradation of aromatic compounds, etc. in bacteria. Several plasmid curing agents have been reported in literature, however, no plasmid curing agent can eliminate all plasmids from different hosts.

Ampicillin is an antibiotic that is usually used as a reporter gene in cloning. A plasmid containing the ampicillin resistance gene (as well as another target gene within the plasmid) is introduced into the bacterial host. If the bacterium has taken up the plasmid and is expressing the plasmid, it will be resistant to ampicillin. LB is used as a growth medium and ampicillin to verify the plasmid is within the bactrium. No growth means no plasmid in the bacterial host...
Plasmids are classified as: 1. F plasmid 2. R plasmid 3. Col plasmid F plasmids for fertility factor, it transfers its plasmid to the non fertile making it fertile. R plasmid for certain antibiotic resisitivity..for eg, ampicillin resistance. Col are certain proteins which when produced doesnt let other organisms to invade its cell.
