Q. Which one of the following is useful in identifying the different strains of a causal microbe of an infectious disease?
A) Colchicines
B) Agrobacterium
C) Complementary DNA
D) Crystal violet
Explanation
Temin and Baltimore (1970) independently discovered enzyme reverse transcriptase in retroviruses (RNA containing viruses). This enzyme can be used to construct a DNA copy, called complementary DNA (cDNA), of any RNA. Thus, this technique can be used in identification of disease causing infectious microbe.
