Autoradiography in DNA fingerprinting is used to--
Options:
Answer:
A
Solution:
In DNA fingerprinting, after the DNA fragments are separated by gel electrophoresis and transferred to a nitrocellulose membrane (Southern blotting), they are hybridized with radioactive VNTR probes.
The hybridized DNA fragments are then detected by exposing the membrane to an X-ray film. This process is known as autoradiography.
Therefore, autoradiography is used to detect hybridized DNA fragments using radioactive probes.
Answer: Detect hybridized DNA fragments using radioactive probes
