In an experiment to extract DNA from something like an onion or strawberry, the last step is to slowly pour ice cold ethanol into the test tube. This causes the DNA to precipitate out of the solution and white stringy material appears a the boundary of the ethanol and prepared DNA solution.
The reason why it happen is because ethanol solution break down the nuclear membrane and cell membrane.
What else can I help you with?
What happens when you put frozen ethanol into liquid ethanol?
When you put frozen ethanol into liquid ethanol, the frozen ethanol will begin to melt and mix with the liquid ethanol. Both states of ethanol will reach an equilibrium temperature, and the frozen ethanol will ultimately dissolve into the liquid ethanol to form a homogeneous solution.
Is distilled ethanol similar to pure ethanol?
Yes, distilled ethanol is similar to pure ethanol. Distilled ethanol is produced using distillation to purify the ethanol, resulting in a high level of purity. Pure ethanol refers to ethanol that is free from impurities, and distilled ethanol typically meets this criteria.
What is the condensed formula for ethanol?
The chemical formula of ethanol is C2H5OH.
What is the word equation for burning ethanol?
Ethanol+oxygen-carbon dioxide+water
The abbreviation of ethanol?
The abbreviation of ethanol is EtOH.
Why methanol is added to ethanol?
To avoid misuse of ethanol for drinking purpose it is denatured with methanol.
What nicknames does Cyrus Ranchhod go by?
Cyrus Ranchhod goes by Icecold.
What should you do if you mix ethanol gas with non ethanol?
to ask for help or try to undo it if on purpose or not for doing projects.
What is the Treatment of internal body fever?
just take a icecold bath this will help to get fever out after that you know what to do
What is the purpose of ethanol in biology?
It's mainly used as a disinfectant and preservative.
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

What is the ratio of ethanol?
The ratio of ethanol to WHAT!
Does ethanol contain water?
Yes, ethanol can contain water as it is a common impurity in ethanol. Ethanol is a type of alcohol that can be mixed with water.
How do you separate ethanol from aqueous ethanol?
Ethanol can be separated from aqueous ethanol through a process called distillation. In distillation, the mixture is heated to evaporate the ethanol, which is then condensed back into liquid form. The condensed ethanol can then be collected as a separate product.
What is the purpose of the condenser in the process of ethanol oxidizing to ethanolic acid?
The condenser is used to cool and condense the vapors produced during the oxidation of ethanol to ethanoic acid. It helps convert the vapors back into liquid form for collection and further processing. This allows for the separation and purification of the ethanoic acid produced during the reaction.
