The clear soap in the DNA extraction experiment serves to break down the cell membranes and nuclear membranes, which are composed of lipids and proteins. By disrupting these membranes, the soap allows the DNA to be released from the cells into the solution. This step is crucial for isolating the DNA so that it can be separated and analyzed.

Why does clear soap help extract DNA from cheek cells?
In eukaryotic cells, which all animal and plant cells are, DNA resides in the nucleus, which is surrounded by a nuclear membrane. The membrane is made primarily of a kind of fat (lipid) molecule called a phospholipid. Lipid molecules repel water, which you know if you have tried to wash greasy dishes in ordinary water -- it doesn't work so well. Soap substances break down the surface tension of water so that water can then dissolve lipids, which is why you have to use soap to wash anything greasy. Soap also dissolves the lipid molecules in the nuclear membrane, so it is helpful in getting the DNA out of the nucleus so it can dissolve freely in the water. Any soap will do, it doesn't have to be clear. The main ingredient of soap which dissolves the lipid membrane is sodium dodecyl sulfate.
What is the purpose of using soap in a DNA extraction buffer?
Soap is used in a DNA extraction buffer to break down cell membranes and release DNA from cells. It helps to disrupt the lipid bilayer of the cell membrane, allowing the DNA to be released into the extraction buffer for further processing and purification.
What is the purpose of copying DNA?
The purpose of copying DNA is that, after mitosis, each daughter cell each has a complete set of DNA and is genetically identical.
What is the purpose of a chromosome?
The purpose is to hold DNA and control your body traits.
What is the order of experiments proving that DNA is the genetic material is?
griffith's experiment
If sperm is on your hand and you wash it can it be trased for DNA purpose?
Yes the DNA can be erased if the hands are washed thoroughly with soap and a good strong disinfectant.
What is the purpose of using sodium chloride in DNA extraction experiment?
if is the best known example mixture
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 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)....

How was human DNA altered in the experiment?
In the experiment, human DNA was altered by introducing specific changes or mutations to the genetic code, either by adding, deleting, or modifying certain segments of the DNA sequence.
What is the purpose of copying DNA?
The purpose of copying DNA is that, after mitosis, each daughter cell each has a complete set of DNA and is genetically identical.
How does salt soap and ethanol extract DNA?
Salt soap helps break down cell membranes, releasing DNA from cells. Ethanol is added to DNA-containing solution to precipitate DNA out of solution, as DNA is not soluble in ethanol. The DNA can then be collected by spooling or centrifugation.
What was the name of the experiment that Meselson and Stahl worked on?
The experiment that supported the hypothesis that DNA replication was semiconservative was known as the Meselson-Stahl Experiment.
What is the Part of an experiment that is not being tested but used for comparison?
Any experiment is associated with a control . This control is actually not a part of experiment itself but is only used to compare the results. for eg in DNA transformation experiments control DNA is also tranformed to analyse and compare the transformation of our required DNA insert.
