Drug resistance in a population of bacteria is inevitable for all of the following reasons EXCEPT... O Bacteria share genetic material through gene transfer mechanisms of conjugation, transformation and transduction. O Bacteria quorum sensing leads to the activation of drug resistant genes. O Bacterial drug resistance genes generally have inducible promoters that are activated when the drug is present. O Bacteria mutate rapidly because of radiation and chemical mutagens.
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
Antibiotic resistance occurs when bacteria change in response to the use of these medicines.some pathogens evolve antibiotic resistance, where they gain traits that allow them to survive in the presence of antibiotics.
Bacteria can share with each other by process called horizontal gene transfer. Gene transfer results in genetic variation in bacteria.
Quorum sensing (QS) is also called density sensing, which controls a variety of physiological behaviors in bacteria.QS system regulates various cellular processes, which mainly involve the regulation of bacterial drug resistance.
