Solution
The correct option is D Prokaryotes
The bacteria (prokaryotes) contain special types of enzymes called the restriction enzymes. These enzymes are responsible for cleaving the viral DNA that enters the bacterial cell for the infection, thereby restricting the growth of the virus particles. Therefore, these are nucleases. These do not degrade the DNA of the bacterial cell because the DNA is protected by methylation. Due to their specific cleaving activity, the restriction enzymes are widely used in rDNA technology.Hence, the correct answer is 'Prokaryotes'
