DNA is a powerful tool because each person's DNA is different from every other individual's, except for identical twins. The act is commonly used to express a multitude of human emotions like love, respect and friendship. Sensitivity-focused assays based on the SRY (single-copy gene) and DYS (multi-copy gene) sequence motifs confirmed the presence of male DNA in female saliva after 10 and even 60min after kissing, respectively. It also can identify a victim through DNA from relatives, even when no body can be found. It depends on a few factors, including the type of food consumed, the amount of saliva produced, and the number of Moreover, in more than one third of samples, it was possible to get the full Y-STR genotype of the relevant male 10min after kissing," the researchers wrote in the study. Cross-Contamination during DNA Collection. Y-STR analysis ignores the contribution of female DNA and focuses only on the male DNA present on the Y chromosome of the sample. These DNA-containing cells are collected, and the DNA is then extracted by various methods. [12] Rogers N.L. How long does someones DNA stay in your mouth?
