Question

Which technique is used in proteomics?

• A. DNA sequencing
• B. PCR
• C. Mass spectrometry
• D. Southern blot

Hint:

Common techniques: \[ \boxed{ \begin{aligned} \text{Genomics} &\rightarrow \text{DNA sequencing} \text{Proteomics} &\rightarrow \text{Mass spectrometry} \end{aligned} } \]

Answer 1

The Correct Option is C

Step 1: Recall the objective of proteomics. Proteomics is the large-scale study of proteins, including their identification, structure, abundance and post-translational modifications.

Step 2: Identify the commonly used technique. Mass spectrometry is the principal analytical technique used for protein identification and characterization. Hence, \[ \boxed{\text{Mass spectrometry}} \] is the correct answer. Therefore, \[ \boxed{(C)} \] is the correct answer.
