Directional Selection
The antibiotic resistance may be transferred to a virulent pathogenic bacterium. Then we will not be able to cure the infection.
The answer to this question would be: Antibiotic
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
They have resistance to the antibiotic.
The answer to this question would be: Antibiotic
The bacteria benefits.
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.
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.

Resistant or resistance is when a bacteria has adapted to an antibiotic.
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.
Horizontal gene transfer is a type of adaptation that allows bacteria to acquire antibiotic resistance genes quickly from other bacteria. This process involves the transfer of genetic material between different bacteria, enabling the rapid spread of antibiotic resistance within a population.
