For example, the DNA in a man's blood is the same as the DNA in his skin cells, semen, and saliva. Because of that difference, DNA collected from a crime scene can either link a suspect to the evidence or eliminate a suspect, similar to the use of fingerprints.

The presence of these carbohydrates does not affect downstream application and therefore A260/A230 is not a useful method to assess the suitability for downstream use of DNA extracted from saliva samples. Neutral bacteria do not affect our health either positively or negatively. Surprisingly, most people assume the source of DNA in saliva is strictly buccal epithelial cells. No matter how fleeting the encounter, the DNA will hang around in their mouth for at least an hour. Secondly, the saliva may not contain enough useful DNA (a point Ill return to below), or the DNA may be too degraded to use. Y-STR analysis ignores the contribution of female DNA and focuses only on the male DNA present on the Y chromosome of the sample. Tens of thousands of researchers and clinicians around the world are already working with saliva due to its high quality performance coupled with quick and easy collection and efficient transport.
