Strain Differences are Helpful In

Question

Strain differences are helpful in
A) understanding replica plating.
B) carrying out electrophoresis.
C) performing transformation in the laboratory.
D) initiating transduction in E. coli.
E) tracing the source of outbreaks of disease.

Accepted Answer

Strain differences are useful in tracing the source of outbreaks of disease. By analyzing the strain differences of the pathogen causing the outbreak and comparing it to strains found in other locations or in other outbreaks, scientists can determine the origin of the outbreak and potentially identify the source of contamination. Strain differences are less relevant for replica plating, electrophoresis, transformation, and transduction, which are mostly concerned with genetic or biochemical processes within cells.
