Question:
Which one of the following is incorrect about DNA microarray?
Which one of the following is incorrect about DNA microarray?
Show Hint
DNA microarray = Global gene expression analysis (not limited to microRNA)
Updated On: May 13, 2026
- It is used for transcriptome analysis
- It is used to identify expression of microRNAs only
- All the expressed genes of a sample can be analyzed simultaneously
- It can qualitatively as well as quantitatively analyze the expression of particular mRNA
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
DNA microarray is a high-throughput technique used to study gene expression patterns.
Step 1: Understand its applications.
• Used for transcriptome analysis → correct
• Can analyze thousands of genes simultaneously → correct
• Provides qualitative and quantitative expression data → correct
Step 2: Identify incorrect statement.
• It is not limited to microRNAs only
• It analyzes expression of many types of genes (mRNA, etc.)
Step 3: Final conclusion.
Thus, the incorrect statement is: \[ It is used to identify expression of microRNAs only \]
Step 1: Understand its applications.
