In conclusion, the extraction of DNA from saliva is a simple process that can be performed at home without the need for sophisticated equipment. Its accuracy is similarly equivalent to DNA obtained from blood. However, unlike the conventional laboratory procedure, which uses blood as an experimental material, the DNA from saliva may be prone to contamination, which may cause the results of the human DNA complete genome sequencing to be misrepresented.

When it comes to privacy issues, it would be ideal to utilize a double-blind storage system, in which the donor names and DNA data are both kept in highly-confidential locations apart from one another. Additionally, DNA samples should not be provided without a contract stating explicitly how and for how long the genetic information will be retained, as well as if it may be used for purposes not expressly stated in the contract. Nevertheless, the best approach to safeguard someone's genetic information is to never reveal it to anyone and to discard it immediately after usage.

In terms of its prospective applications in the disciplines of genealogy, personalized medicine, and DIY genetic testing, this technology may be used to discover information about an individual's history as well as probable illnesses and body issues. Furthermore, it might be utilized to detect early indicators of disease, provide individualized diagnostics, and modify therapy targets.

Lastly, understanding DNA extraction is significant because it could inform people about the various DNA extraction techniques, the drawbacks of the at-home DNA extraction method, the quantity and quality of the extracted DNA from the saliva, the potential applications of this method in various gene-related fields, the safeguards to ensure the privacy of an individual’s genetic information and the precision of the DNA extracted from saliva. All in all, the DNA extraction experiment may increase people’s awareness and engagement with genetic concepts.
