Isopropanol is more preferred than ethanol in DNA extraction, as isopropanol facilitates precipitation more better, as it possess very less i.e., 0.6 to 0.7 volumes of alcohol.
To concentrate or purify the DNA, which is insoluble in isopropanol. Once the solution containing your DNA is placed in isopropanol and centrifuged, the DNA will precipitate to a little pellet at the bottom of your tube. Everything else in your tube is soluble in isopropanol and will remain in liquid form. Pipet the liquid out and now you have just DNA.
Not adding ethanol during DNA extraction can prevent the precipitation of DNA, as ethanol is crucial for separating DNA from the aqueous solution. Without ethanol, DNA remains dissolved in the liquid, making it difficult to isolate and collect. This can lead to low yields or no recovery of the desired DNA, hindering further analysis or applications.
Ethanol is commonly used in DNA extraction because it effectively precipitates DNA from aqueous solutions, allowing for easy separation and purification. In RNA extraction, isopropyl alcohol is preferred because it provides higher yields and better purity of RNA, which is more sensitive and prone to degradation. Additionally, isopropyl alcohol helps to minimize the co-precipitation of contaminants and proteins, ensuring a cleaner RNA sample.
Hydrochloric acid (HCl) is not typically used in the isolation of DNA. Instead, common methods for DNA extraction involve using detergents to lyse cells, along with salt solutions to precipitate proteins and other cellular debris. Ethanol or isopropanol is then used to precipitate the DNA from the solution. While HCl can be used in some biochemical applications, it is not standard in DNA isolation processes.
Isopropanol is used in RNA extraction to precipitate RNA from the sample solution. By adding isopropanol to the sample, RNA molecules clump together and can be separated from the rest of the components in the solution using centrifugation. This allows for the isolation of RNA for further analysis.

Ethanol is used after the chloroform and isoamylalcohol mixture to precipitate DNA from the solution. Isopropanol is used during genomic DNA isolation to further facilitate the precipitation of DNA, ensuring a higher yield and purity of DNA in the final step.

70% ethanol is used in DNA extraction to wash and precipitate DNA from a sample. Ethanol helps to remove impurities and salts, allowing DNA to clump together and be easily separated from the rest of the sample. It also helps to preserve the integrity of the DNA during the extraction process.
Ethanol precipitates DNA during the extraction process because DNA is not soluble in ethanol. When ethanol is added to the DNA solution, the DNA molecules become less soluble and clump together, forming a visible precipitate that can be collected and separated from the rest of the solution.

To precipitate the DNA out of solution. It is usually done in the presence of salt, such as sodium chloride or potassium sulfate. This process is called "salting out", meaning becoming out of solution (water), which also can be done with other electrically charged molecules (ionized), including proteins.
Cold ethanol is used in DNA extraction because it helps to precipitate the DNA molecules out of the solution. When DNA is mixed with cold ethanol, the DNA molecules become less soluble and clump together, making it easier to separate them from other cellular components. This process allows for the isolation and purification of DNA for further analysis.
Sodium citrate is used in DNA extraction to help neutralize the charge on DNA molecules, making them more insoluble in alcohol. This helps to precipitate the DNA out of solution, allowing for easier isolation and purification of the DNA.
