First, avoid kissing people you dont know. Kissing also stimulates the brain hormones, dopamine and oxytocin both of which promote bonding and attachment in human beings. It can lead to cold sores. It therefore opens the way for convenient point of care testing[9], Abraham J.E et al. DNA degrades over time, and just how long it lasts depends on how well its preserved. Overall, saliva is less expensive than blood for DNA collection when factoring in all costs associated with the sample collection procedure. Step 2: Separate DNA from other parts of the cell such as proteins. The male cells were selected and isolated from the female DNA through laser micro-dissection and were extracted and analyzed with conventional DNA typing kits. Further, just like fingerprints, DNA testing cannot tell officers when the suspect was at the crime scene or for how long. However, many people dont know that replacing blood with saliva is a proven option for genomic DNA analysis. Paternity refers to fatherhood.
