Where can one get his DNA extracted?
One can get his DNA extracted at a crime laboratory, at a police precinct, at a hospital, and even at home. DNA can be extracted by using a cotton swab in the inside of one's cheek or through a blood sample.
What human cells can't have DNA extracted?
Red blood cells (otherwise known as erythrocytes). They contain no DNA or organelles. They lose them whilst maturing so as to be able to pack more haemoglobin into the cell and therefore be more efficient oxygen carriers.
What food can DNA be extracted from?
DNA can be extracted from any living organism that has cells containing a nucleus, such as fruits, vegetables, meat, fish, and plants. Common sources for extracting DNA in a lab setting include strawberries, bananas, and onions.
How old can blood be before you can not get DNA from it?
Under ideal conditions, DNA can be extracted from blood samples that are decades old. However, the quality and quantity of DNA deteriorate over time due to factors such as degradation, contamination, and storage conditions. For reliable results, it is generally recommended to extract DNA from blood within a few days to a few years after collection.
Why chilled ethanol is added for DNA isolation?
to precipitate extracted DNA

How is DNA extracted from blood samples?
DNA is extracted from blood samples by first breaking open the cells to release the DNA. Then, the DNA is separated from other cellular components using a series of chemical and physical methods. Finally, the purified DNA is collected and can be used for various genetic analyses.
What is the source of DNA in blood?
DNA in blood comes from white blood cells, which contain the person's genetic information. When blood is collected for testing or analysis, the DNA can be extracted from these cells to study and identify specific genetic markers or sequences.
Can a sample of blood from a piece of clothing be use for DNA testing?
Yes, a sample of blood from a piece of clothing can be used for DNA testing. The DNA extracted from the blood can be compared to known DNA samples to help identify a person or provide information about their biological relationships.
How long will extracted DNA last if frozen?
Extracted DNA can last indefinitely if properly stored in a freezer.

Can DNA be collected from your bones?
Yes, DNA can be collected from bones. Bone tissue contains osteocytes, which have DNA that can be extracted and analyzed. This process is particularly useful in forensic science and archaeology for identifying individuals or determining genetic relationships, even in cases where other forms of DNA sources, like blood or saliva, are not available. However, the quality and quantity of DNA extracted from bones can vary based on the age and condition of the bones.
Could DNA extracted from onion be different from DNA extracted from cauliflower why?
Although DNA is composed of the same four nucleotides in all organisms, the sequence of nucleotides is different for each species
How is DNA extracted from Red Blood Cells?
