What differentiates diagnostic techniques that employ phenotypic (culture-based)methods from those that employ molecular methods?
A)Phenotypic methods are highly sensitive and specific,while molecular methods are not.
B)Phenotypic methods examine the growth behavior of a microorganism and the proteins,enzymes,or toxins produced,while molecular methods examine the genetic makeup.
C)Phenotypic methods are quantitative while molecular methods are not.
D)Phenotypic methods are not limited to detection of live organisms as are molecular methods.

Question

Quizplus · Accepted Answer

Molecular methods involve the detection and manipulation of nucleic acids (deoxyribonucleic acid [DNA] and ribonucleic acid [RNA])allowing microbial genes to be examined directly (i.e. ,genotypic methods)rather than by analysis of their products,such as enzymes,other proteins and toxins,or identifiable characteristics of organism growth (i.e. ,phenotypic methods).
