JordanTris-Borate-EDTA (TBE) buffer is commonly used in DNA extraction procedures to provide a suitable pH and ionic environment for DNA stability. TBE helps to maintain the integrity of DNA by preventing degradation, facilitating electrophoresis, and providing conductivity for the separation of DNA fragments.

What is function of glucose in DNA extraction?
Maintaining the osmotic pressure to prevent the cell form bursting.
What is the function of dithiothreitol in DNA extraction?
Dithiothreitol (DTT) is a reducing agent used in DNA extraction to break disulfide bonds in proteins, helping to denature and separate them from DNA. This helps to prevent protein contamination in DNA samples, ensuring the purity of isolated DNA.
What is the function of 2-propanol in DNA extraction?
2-propanol is used in DNA extraction to precipitate DNA from the mixture. When added to the sample, it causes the DNA molecules to come out of solution and form a visible clump that can be easily separated. This step allows for the separation and purification of DNA from other components in the sample.
What is the function in the following reagents used in the extraction and precipitation of DNA?
The function of phenol-chloroform is to denature proteins and extract DNA into the organic phase, while the function of isopropanol is to precipitate DNA by causing it to become insoluble in the solution.
What is function of Buffer AP1 in DNA extraction?
Buffer AP1 is used in DNA extraction to lyse cells and release nucleic acids. It contains a chaotropic salt that disrupts cell membranes and denatures proteins, allowing DNA to be released from the cells. Buffers with chaotropic salts help to preserve the integrity of DNA during the extraction process.
