Nohern blot test is used for?
DNA analysis
RNA analysis
Analysis of proteins
Enzyme analysis
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.
