Because they dont have a nucleous.

Chloroform is used in DNA extraction to separate DNA from proteins and lipids. It helps to denature and precipitate the proteins and disrupt the cell membranes to release the DNA. The DNA can then be further purified and isolated for downstream applications.
Toasted wheat germ contains compounds that can interfere with the DNA extraction process, such as fats and proteins. These compounds can inhibit DNA isolation and purification by binding to or degrading the DNA molecules. It is recommended to use fresh, unprocessed wheat germ for successful DNA extraction.
The elution buffer is used in DNA extraction to release the purified DNA from the column by breaking the bonds between the DNA and the column material. This allows the DNA to be collected in a separate tube for further analysis or use.
one of the matherials that we use for this is cloroform. others...
Use the usual extraction protocol for plants: grind, liquid-liquid extraction, salting out.
Ammonium acetate is used in DNA extraction to precipitate DNA from solution. It helps to neutralize the pH of the solution and allows DNA molecules to form a complex with the acetate ions, leading to DNA precipitation. This facilitates the separation of DNA from other cellular components.
Yes, saline citrate buffer can be used for DNA extraction from bivalve tissue. It helps in breaking down cell membranes and proteins, releasing the DNA for further extraction and purification steps. Ensure to follow a tested protocol for optimal results.
Salt was used in the extraction solution to help separate the DNA from other cellular components by creating a high-salt environment that causes the DNA to clump together and precipitate out of the solution.
Chloroform isoamylalcohol is used in DNA extraction to separate DNA from other cellular components by forming a separate layer due to differences in density. It helps in denaturing proteins and disrupting cell membranes, allowing the DNA to be released into the aqueous phase for further purification. Additionally, the isoamylalcohol helps to prevent foaming during the extraction process.
Molecules that can interfere with DNA extraction include proteins, polysaccharides, lipids, and polyphenols. These molecules can bind to DNA, causing it to be more difficult to extract or making the DNA susceptible to degradation during the extraction process. It is important to use appropriate methods to remove or inhibit these molecules before extracting DNA from cells.
A mesh particle size of 50-100 μm is commonly recommended for the use of Chelex 100 resin in DNA extraction procedures. This size allows for efficient binding of DNA while minimizing binding of larger molecules like proteins and polysaccharides.
