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.
Both cheek-swab DNA tests and blood-drawn DNA tests are methods used to obtain a sample of DNA for genetic testing. They both provide genetic information that can be used for various purposes such as ancestry testing and health risk assessments. Cheek-swab tests are non-invasive and can be done at home, while blood-drawn tests require a visit to a healthcare provider for sample collection.
Yes, tobacco smoke can potentially contaminate a DNA swab by introducing foreign DNA that may interfere with the analysis. It is recommended to collect DNA samples in a smoke-free environment to prevent contamination.
Swabbing the inside of cheeks is a simple and non-invasive way to collect DNA samples, as the cells lining the cheeks contain DNA. This method is convenient, painless, and does not require a blood sample. The DNA collected from the cheek swab can be used for various genetic tests and analysis.
In most of the countries the police are not allowed to get your DNA sample without the permission of the court.
A swab taken from you would contain your DNA and thus match your DNA. A swab taken from the alleged victim would contain the victim's DNA and thus match the victim's DNA. What would be shocking is if the swab taken from you didn't match your DNA, or the victim's swab didn't match their DNA. Therefor, it means that you are you, and the alleged victim is the alleged victim.
It means that you are related

DNA
A DNA swab is the most common method of collection of DNA. The swab is swiped inside the cheek to collect epithelial cells and placed in a sterile tube until tested.

Not always.

There is always a way to mess up a test, most would be caused by human error. This could be due to using a swab to obtain cheek cells and thereby DNA not being sterile. If the swab is not sterile then it could have DNA on it from unknown sources all the way back to the person at the factory that made said swab. Additionally, if the person taking the sample is not careful he/she could contaminate it with their own DNA or DNA present in the environment before or after sampling. Of course the test could be messed up simply because the DNA amplification was performed incorrectly or insufficient starting material was obtained.
The swab used in cheek swab DNA testing is already sterile and ready for testing when you purchase it. They are designed for single use so only use it on the person being tested. If multiple people are being tested, use the multiple swabs included in the home DNA kit. Lastly, don't drop the swab. Contamination from dropping the swab could definitely affect the accuracy of the test results.
No, that is not how it works.
Yes - if they didn't use a condom. She can take a swab of the inside of her vagina, and send it to a lab for DNA analysis.
