1.role of methanol in this practical
Methanol is used in DNA isolation to precipitate DNA from the solution. It causes DNA molecules to come out of the solution, facilitating their separation and purification.
Methanol is added to the DNA solution to lower its solubility, causing DNA to precipitate out of the solution. This precipitation allows for easy isolation and purification of the DNA.
2.why we use cold methanol or ethanol reason
Cold temperatures increase the solubility of salts while reducing the solubility of DNA, leading to the precipitation of DNA strands. This step helps in obtaining a higher yield of pure DNA during the isolation process.
3.role of detergent in this practical
Detergent is added during DNA isolation to break down cell membranes and nuclear envelopes, releasing cellular components, including DNA, into the solution.
4.role of NaCl in this practical
NaCl is used in DNA isolation for its role in maintaining ionic strength, aiding DNA precipitation, and facilitating protein separation. It also helps stabilize DNA and ensures optimal conditions for the isolation process.

Nice sir, why you can't use sodium laureal sulphate or sodium dodecyl sulphate.

[@LetMeExplainnowbharatpanwar]

Sodium lauryl sulfate (SLS) and sodium dodecyl sulfate (SDS) are detergents commonly used to disrupt cell membranes in various experiments. However, they are not ideal for DNA isolation practicals for several reasons:
1. **Protein Denaturation:** SLS and SDS are strong protein denaturants. While they effectively break down cell membranes, they also denature proteins, making it challenging to isolate intact, functional DNA.
2. **Enzyme Inhibition:** DNA isolation often involves enzymes that are sensitive to denaturation by these detergents. The use of SLS or SDS can inhibit the activity of these enzymes, affecting the overall success of the isolation process.
3. **Precipitation Issues:** SLS and SDS can interfere with DNA precipitation steps. They may remain in the solution and affect the purity of the isolated DNA.
For DNA isolation, milder detergents, such as Triton X-100, are preferred. These detergents effectively disrupt cell membranes while minimizing interference with DNA structure and enzyme activity, resulting in better-quality DNA isolation.
