Nohern blot test is used for?
Correct Answer: RNA analysis
Description: The nohern blot is used to demonstrate specific RNA. The total RNA is isolated from the cell, electrophoresed and then blotted to a membrane. This is then probed with radioactive cDNA. There will be RNA-DNA hybridization, if the specific RNA is present in the cell. For DNA analysis southern blot technique is used, western blot analysis is used to identify proteins.Also Know:A fouh hybridization technique, the Southwesternblot, examines protein-DNA interactions. In this method, proteins are separated by electrophoresis, blotted to a membrane, renatured, and analyzed for an interaction with a paicular sequence by incubation with a specific labeled nucleic acid probe.
