Because the fragments that can have DNA extracted are quite small and can't even give evidence, describe or identify one single gene.
It is difficult to extract DNA from fat tissue because of the high lipid content in the cells. Lipids can interfere with the DNA extraction process by binding to the DNA and preventing it from being isolated effectively. Specialized protocols and reagents are needed to remove the lipids and extract the DNA successfully from fat tissue.
Cooking food denatures the proteins and breaks down the cell structures, potentially damaging the DNA. The high temperatures used in cooking can degrade and fragment the DNA, making it difficult to extract intact DNA for analysis. Additionally, enzymes that break down DNA may be present in cooked food, further complicating the extraction process.

Yes.
Yes, it is possible to extract DNA from ear wax as it contains skin cells that can be used for genetic testing.
Yes, it is possible to extract DNA from blood samples. This process involves isolating the DNA molecules from the blood cells and purifying them for analysis or testing.
Yes, it is possible to extract DNA from sweat. Sweat contains skin cells that may contain DNA, which can be extracted using specialized techniques for analysis and identification.
Because the purpose of this lab is to extract DNA from a variety of cells and see DNA
scientists take the DNA exactly how they do liike humans no diifference
We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes, RBCs are not good source of extraction but we can extract DNA from immature RBCs.
Ethanol is used to extract DNA because it is able to precipitate the DNA out of solution due to its nonpolar nature. When added to a DNA solution containing salt, the DNA molecules become less soluble in ethanol and can be easily collected by precipitation with a centrifuge.
