There are hydrophobic amino acids and hydrophilic amino acids in protein molecules. After protein folding in aqueous solution, hydrophobic amino acids usually form protected hydrophobic areas while hydrophilic amino acids interact with the molecules of solvation and allow proteins to form hydrogen bonds with the surrounding water molecules. If enough of the protein surface is hydrophilic, the protein can be dissolved in water.
When the salt concentration is increased, some of the water molecules are attracted by the salt ions, which decreases the number of water molecules available to interact with the charged part of the protein. As a result of the increased demand for solvent molecules, the protein-protein interactions are stronger than the solvent-solute interactions; the protein molecules coagulate by forming hydrophobic interactions with each other. This process is known as salting out.

The salting out method for genomic DNA isolation relies on the principle that high concentrations of salts disrupt the interactions between DNA and proteins, leading to precipitation of proteins. By adding a high-salt buffer to a cell lysate, proteins will precipitate out of solution, leaving the DNA behind in the supernatant. The DNA can then be further purified using ethanol precipitation or other methods.

Source(s):WikikpediaTo isolate genomic DNA from groundnut leaves, you can use a commercial DNA extraction kit designed for plant tissue. Follow the kit's protocol, which usually involves grinding the leaves in a lysis buffer, isolating the DNA through purification steps, and then eluting the DNA in a suitable buffer. Ensure that you properly store the extracted DNA at -20°C to -80°C for later use.
Yes, both streaking for isolation and streaking for antibiotic sensitivities use the same basic streaking technique. However, the purpose and method of interpretation are different. Streaking for isolation is to obtain pure colonies of a microorganism, while streaking for antibiotic sensitivities is to test the susceptibility of the microorganism to specific antibiotics.
Fluorine was obtained by the hydrolysis of a mixture of KF2 and HF.
the methods of preparing aromatic waters are: 1. by distillation 2. by solution 2.1.by direct solution 2.2. by alternate solution
Depending on the type of the food many methods of preservation exist: adding sugar, salting, irradiation with gammas, freezing, lyophilisation, pasteurization etc.
Salting food is a method of preserving it.
BSI, or Body Substance Isolation.
The salt simply acts as a preservative. People have been preserving meat by the salting method for centuries.

They are both the same. displacement method is another name for Archimedes' principle

Drying food in the sun/air. Smoking food in the smoke from a fire. Salting food (and then perhaps smoking it).
the principle of this test are used the method of a qualitative test for the detection of nematode and cestode eggs and coccidia oocysts in the faeces.

One method is to send Viral to his bedroom without supper.

It leads to speciation. many species in nature have evolved by this method.
