What is preferred in DNA extraction ethanol or isopropanol and why?
Isopropanol is more preferred than ethanol in DNA extraction, as isopropanol facilitates precipitation more better, as it possess very less i.e., 0.6 to 0.7 volumes of alcohol.
Why we use two washing buffers in DNA extraction using biosprint?
the washing buffers contain ethanol which precipitating DNA molecules and form clumps. DNA is insoluble in alcohol so come together in an alcohol buffer.
Can iso amyl alcohol replace phenol in DNA extraction?
No
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.
What is the function in the following reagents used in the extraction and precipitation of DNA?
to extract the DNA from the solution, isopropyl alcohol is mixed with the DNA solution to precipitate the same.

What does sodium citrate do in DNA extraction?
how to make sodium citrate in 10% ethanol for DNA extraction

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.
Can iso amyl alcohol replace phenol in DNA extraction?
No
What is the function of the alcohol in DNA extraction?
DNA is not soluble in isopropyl alcohol. It will precipitate out when you add this solvent. Once out of solution you can centrifuge it down and collect the pellet of DNA.
What is DNA extraction?
There are three basic steps in a DNA extraction, the details of which may vary depending on the type of sample and any substances that may interfere with the extraction and subsequent analysis. * Chelate divalent cations such as Mg2+ and Ca2+ to stop dnase enzymes functioning and degrading the DNA * Break open cells by grinding or sonication, and remove membrane lipids by adding a detergent. * Precipitate DNA in cold ethanol or isopropanal, DNA is insoluble in alcohol and clings together; this step also removes salt.
What is the purpose of alcohol when extracting DNA?
According to me, we use alcohol because DNA is insoluble in alcohol, it aggregates together, giving a pellet in centrifugal and we can see a precipitated DNA with naked eyes (that we suppose to see in experiment i.e DNA extraction)....

What are the precaution while conducting DNA extraction?
Perhaps the most basic precaution is to make sure that the warm water bath that will be used has a temperature that doesn't exceed 90C so as to denature only the protein component of crude extract and not the DNA which is the target isolate.
What is the purpose of soap in strawberry extraction?
The purpose is to help the mixture of salt water and ethanol so the can find the DNA of strawberry bananna etc. Extrsctions
