D. Focusing
Sound waves reflected in flat surfaces like walls, floors and ceilings results to uneven dispersion of sounds by creating locations with high intensity and another with low intensity. This process is called Focusing and can be undesirable in auditoriums.
Answer:
All require at least one protein cofactor.
Explanation:
Translation is the process of the formation of the proteins from the different RNA molecules, enzymes and the cofactors. The translation process involves the movement of ribosomes over mRNA.
The three important process of translation are initiation, elongation and termination. All these steps require different enzymes and protein cofactors. The initiation requires the initiation cofactors like eIF, elongation require additional cofactors and same with the termination of translation.
Thus, the correct answer is option (1).
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.
