Which of the following can be used to study the bacterial proteome?
A) DNA microarrays
B) pyrosequencing
C) two-dimensional gels and mass spectrometry
D) green fluorescent protein
E) networking with nanotubes

Question

Quizplus · Accepted Answer

Two-dimensional gels can separate proteins based on their isoelectric point and molecular weight, and mass spectrometry can identify the proteins present in the sample. This technique is commonly used to study the bacterial proteome.

A) DNA microarrays are used to study gene expression, not protein expression. 
B) Pyrosequencing is a DNA sequencing method, and does not provide information on protein expression. 
D) Green fluorescent protein is a protein tag or marker, which can be fused to another protein to track its location or expression, but it does not provide information on the entire proteome. 
E) Networking with nanotubes is not a technique used in proteomics.
