Different between CTAB method and Dellaporta method?
In CTAB method,SEVAG is used to breakdown the tissues in the extracted leaves.While in dellaporta method,the SDS and POTASSIUM ACETATE are used.In CTAB method BLUECAP/TEST TUBES are used,while in dellaporta method the EMPENDORFS are mostly used.ICE COLD ETHANOL is used mostly in the CTAB method for resuspension,while in dellaporta method ISOPROPANOL is used.
What is the importance of ctab buffer?
CTAB buffer, or cetyltrimethylammonium bromide buffer, is commonly used in DNA extraction protocols to lyse cells and separate DNA from proteins and other cellular components. It is important because CTAB helps to solubilize cell membranes and organelles, allowing for the isolation of high-quality DNA. CTAB also helps to remove contaminants that could inhibit downstream applications such as PCR.
Why use CTAB in DNA isolation?
The CTAB extraction procedure is from Rogers and Bendich (1986). The magic bullet is supposed to be the separation of polysaccharides from nucleic acids by the use of CTAB. The technique capitalizes on the previous observations that nucleic acids can be selectively precipitated with CTAB. RNA and DNA are soluble in CTAB and 0.7 M NaCl but precipitate when the salt is reduced below 0.4 M. However, many polysaccharides are insoluble over this salt range and are thus not solubilized. CTAB is NOT used to lyse membranes in this procedure.
Role of ctab in isolating DNA from soil sample?
CTAB is a surfactant used in the isolation of DNA from tissues containing high amounts of polysaccharides. Under the high-salt conditions of this protocol, CTAB binds the polysaccharides removing them from the solution. When combined with Arabidopsis, this procedure yields pure DNA.
What is the alternative term for sugar in the field of biology?
The alternative term for sugar in the field of biology is "carbohydrate."

Why in DNA isolation ctab method used chloroform isoamylalcohol?
Chloroform isoamylalcohol is used in the CTAB method of DNA isolation to separate the DNA from proteins and lipids present in the sample. The mixture of CTAB, chloroform, and isoamylalcohol helps to denature proteins, dissolve lipids, and create separate phases in which DNA can be extracted. This method allows for efficient purification of DNA from the complex biological sample.
What is the difference between CTAB and SDS method?
This refers to the type of detergent used to lyse cell membranes when extracting DNA from cells. SDS=Sodium dodecyl sulfate, CTAB=Cetyl trimethylammonium bromide
What is CTAB buffer- its full meaning?
CTAB stands for cetyltrimethylammonium bromide. CTAB buffer is a solution containing CTAB and other components used in molecular biology techniques to isolate DNA or RNA by disrupting cell membranes and protein interactions. It helps in the purification and extraction of nucleic acids from biological samples.

Is octanol soluble in water?
Octanol is sparingly soluble in water because of its hydrophobic nature. The long hydrophobic carbon chain in octanol is not favorable for interaction with water molecules, preventing it from dissolving easily in water.
What is the smell of octanol?
Octanol does not have a specific smell as it is a chemical compound. However, some people may describe the smell of octanol as slightly floral, fruity, or waxy. It is important to note that individual perceptions of smell can vary.
Can octanol float on water?
Octanol is less dense than water, so it can float on the surface of water. This is because octanol is an organic compound with a lower density than water, allowing it to remain on top when the two liquids are combined.
What is the molar heat of combustion of 1-octanol?
The molar heat of combustion of 1-octanol is approximately -6,268 kJ/mol. This value represents the amount of heat released when one mole of 1-octanol is completely burned in excess oxygen to form carbon dioxide and water.
What is the molecular formula of CTAB?
[(C16H33)N(CH3)(CH3)(CH3)]BrCHEMICAL NAME - Cetyl Tri Methyl ammonium Bromide
Role of CTAB in DNA isolation?
It sequester carbohydrates in the solution
