Some membranes are positively charged and therfore they can electrostaticaly bind negatively charged DNA. Exposing of membrane with electrostaticaly bound DNA to UV light will make make covalent binds between membrane and DNA.
The answer is NO! To me, it makes no sense, why we have to transfer etbr with DNA to a blotting membrane? When Southern blotting signals will be detected by means of Radiochemicals or fluro labelling why we have to think about EtBr?
When probes are added to a nylon membrane, they bind specifically to complementary nucleic acid sequences that may be present on the membrane. This process, known as hybridization, allows for the detection of specific DNA or RNA sequences. The nylon membrane typically retains the bound probes, enabling subsequent washing and detection steps to identify the presence of the target sequences. This method is commonly used in techniques such as Southern or Northern blotting for molecular analysis.

A nylon membrane is a type of filter commonly used for molecular biology techniques such as Southern and Northern blotting. It allows for the transfer and immobilization of DNA or RNA molecules from a gel onto the membrane for further analysis, such as probing for specific sequences or gene expression levels.
So that your DNA does what it needs to do for your body.

Placing a nylon membrane over an electrophoresis gel is typically done for transferring DNA or proteins from the gel onto the membrane, a process known as Southern or Western blotting. This allows for subsequent detection of specific target molecules present in the sample.

DNA is not typically found in the cell membrane. DNA is mainly located in the cell nucleus, where it carries genetic information. Certain organelles, like mitochondria and chloroplasts, also contain DNA, but it is not associated with the cell membrane.
During an RFLP (Restriction Fragment Length Polymorphism) analysis, DNA is digested with restriction enzymes, separated by gel electrophoresis, and transferred to a membrane for hybridization with a probe. The resulting pattern of DNA fragments of varying lengths is visualized to identify variations in DNA sequences between individuals.
Southern Blotting refers to the identification of detailed sequences of DNA in which the DNA fragments are separated by electrophoresisNorthern Blotting refers to the identification of detailed sequences of RNA in which the RNA fragments are separated by electrophoresis
