Which one of the following analytical techniques does not help illuminate a gene's cellular function?
A)DNA microarray analysis
B)Protein chip analysis
C)Southern blotting
D)Two-dimensional gel electrophoresis
E)Two-hybrid analysis

Question

Quizplus · Accepted Answer

Southern blotting is a technique used to detect the presence of a specific DNA sequence in a sample, but it does not provide information about the function of a gene in the cell. The other techniques listed (DNA microarray analysis, protein chip analysis, two-dimensional gel electrophoresis, and two-hybrid analysis) can all provide insight into a gene's cellular function by identifying its interactions with other molecules or its expression level in different conditions.
