Answer:
The correct answer is option b, that is, a modification in the target of DNA gyrase, is an illustration of acquired resistance.
Explanation:
The activity of DNA gyrase gets inhibit by fluoroquinolones. The enzyme that combines with the DNA and prevents its supercoiling at the time of replication is termed as DNA gyrase. It is a heterotetramer, which is formed of two subunits of GyrA and two subunits of GyrB. Due to the mutation in gene gyrA, the development of resistance takes place in N. gonorrhea against fluoroquinolones.
Post mutation, gyrA exhibits lesser binding capacity with the fluoroquinolones, and thus, the development of resistance takes place within the bacteria against the fluoroquinolones. The phenomenon of the development of resistance taking place in any microbe against the specific antimicrobial agent for whom it was vulnerable before is termed as acquired resistance, thus, the given case is an illustration of acquired resistance.
