Why are methanol and ethanol not used for extractions?
They are used in liquid:liquid extractions, methanol especially. What extraction are you performing? plant extraction for antimicrobial activities and phytochemical ivestigation
Role of phenol chloroform isoamyl alcohol in plasmid DNA extraction?
The actual role of phenol chloroform isoamyl alcohol in a plasmid DNA extraction is to purify the DNA. The alcohol will act in part as a detergent.
How does methanol react with water?

Would methanol be a better or poorer solvent for extraction of cholesterol from egg yolk compared to 2-propanol?
The solubility of cholesterol in methanol is 0.014. 2-propanol would be a better solvent than methanol for the extraction of cholesterol from egg yolk.
How do you separate methanol from surfactants?
There are a number of methods that can be used to separate methanol from surfactants. The most effective method is extraction of the cationic surfactants by contracting the mixture with water.
Is chlorophyll a pigment?

If you fixed a tissue in ethanol that have methanol or other toxic material and then you extract DNA from it does the DNA functionable for PCR?
It depends on the method of extraction. Extraction that involve the use of resins of ionic exchange or affinity should be able to eliminate other substances.
