Bacterial resistances are developed due to mutations that are passed down from generations of bacteria. Antibiotics generally kill all but the strongest bacteria or bacteria that have resistances to these antibiotics, resulting in only these bacteria reproducing, passing on the antibiotic resistances to future generations. Over time, entire populations of bacteria can develop a resistance to an antibiotic if they are frequently exposed to it.

True or false cells containing a plasmid with an antibiotic resistance gene will die in the presence of the antibiotic?

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.


What type of plasmid is the source of the problem with antibiotic resistance?

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.


Is resistance to antibiotics permanent?

Resistance to antibiotics is not necessarily permanent. Some bacteria can lose their resistance if they are not constantly exposed to antibiotics. However, the emergence of new mutations can result in the development of new antibiotic-resistant strains. Continued monitoring and appropriate use of antibiotics are essential in managing antibiotic resistance.


What mutations cause antibiotic resistance in bacteria?

Antibiotics are generally targets a potential life process of pathogen. If a pathogen mutates its protein for example it may be complete different than the previous and may even changes its function slightly different. Thus the antibiotic that are acting on the previous form of a protein acts no more on this newly mutated protein because of its specificity.


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

How antibiotics resistance occur?

Antibiotic resistance occurs when bacteria or other microbes builds the ability to resist the effects of the antibiotic. This happens when bacteria changes in a way that reduces or eliminates the effectiveness of the drugs designed to cure infections.


What is the Medical term meaning superbug infection?

Antibiotic resistance is a type of drug resistance where a microorganism is able to survive exposure to an antibiotic.

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.


How is antibiotic resistance an adaptation?

The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.


Has antibiotic resistance affected endocarditis?

Unfortunately, in recent years, the treatment of endocarditis has become more complicated as a result of antibiotic resistance

Why do plasmids contain a gene for antibiotic resistance?

Plasmids contain antibiotic resistance genes because these genes provide a survival advantage to the bacteria in the presence of antibiotics. Bacteria can pick up plasmids with antibiotic resistance genes through horizontal gene transfer, allowing them to survive in environments with antibiotic exposure. This is a common mechanism for bacteria to acquire resistance traits and poses a challenge for antibiotic treatment.


When bacteria are not affected by antibiotics they have?

They have resistance to the antibiotic.


Antibiotic in gene cloning?

If antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all non-transformed bacteria, that don't have the antibiotic resistance. There is a chance that the non-transformed bacteria can mutate to develop antibiotic resistance.


Is it true cells containing a plasmid with an antibiotic resistance gene will die in the presence of the antibiotic?

false


What can gene for antibiotic resistance be used for?

genetic marker
