Correct option is A
Explanation-
Option a - Western Blotting
This is used for the detection of proteins, not DNA. It uses antibodies to detect specific proteins after electrophoresis.
Option b - Polyacrylamide Gel Electrophoresis (PAGE)
PAGE can be used to separate small DNA fragments or oligonucleotides. It is commonly used for DNA sequencing gels.
Option c - Fluorescence Microscopy
Fluorescent dyes like DAPI or ethidium bromide are used to stain and visualize DNA. It is suitable for DNA visualization.
Option d - Denaturing High-Performance Liquid Chromatography (DHPLC)
This can be used for mutation detection and separation of DNA fragments based on sequence differences and suitable for DNA.
Correct Answer:
Option 1. Western Blotting
Because it is not used for DNA, it is used for proteins.
