Solution

The correct option is C Lactamase
Antibiotics are antibacterial compounds produced by the bacteria or obtained synthetically. They are used in treatment of various bacterial infections. However,s some bacteria shows resistance to certain antibiotic. Beta-lactamase is an enzyme produced by bacteria that provide resistance to antibiotics ampicillin, cephalosporin. These antibiotics are made up of β-lactam ring. Lactamase enzyme breaks the β-lactam ring open and hence deactivate the antibiotic.
Thus, the correct answer is 'Lactamase.'

Q. The growth of ampicillin resistant bacterial population (strain 1) infected by a virus declines as the virus enters lytic cycle. Then the virus undergoes lysogenic cycle and further remove themselves from bacterial genome during heat shock treatment to proteins. All the bacteria die after some time and only free virus now can grow. A second bacterial ampicillin sensitive population (strain 2) is the infected by this virus. Similarly the bacterial population decreases and ampicillin population rebounds.

Which of the following phenomenon is responsible for the development of ampicillin resistance by bacterial strain 2?

Q. Ampicillin-sensitive bacteria are exposed to a plasmid containing the gene for resistance to the antibiotic ampicillin. They are then spread on two agar growth plates. Plate A contains growth medium only. Plate B contains growth medium and ampicillin.
Which plate might be expected to have cultures of ampicillin-resistant bacteria growing on it?

Q. If a recombinant DNA bearing gene for resistance to antibiotic ampicillin is transferred to E.coli cells, the host cells become transformed into ampicillin-resistant cells. If such bacteria are transferred on agar plates containing ampicillin, only transformants will grow and the non-transformed recipient cells will die. The ampicillin-resistant gene in this case is called as _______________.

Q. The bacterial antibiotic resistance genes are usually present in _____
