To take out the useful parts of the food, the digestive system breaks the food down into small pieces. This process is called digestion. The parts of the food which are not useful just pass through the body.
The interrogation. Interrogations consist of three pulses, 0.8 Î¼s in duration, referred to as P1, P2 and P3. The timing between pulses P1 and P3 determines the mode (or question) of the interrogation, and thus what the nature of the reply should be. P2 is used in side-lobe suppression, explained later.
Organic extraction: 4 hours 30 minutes Organic differential extraction: 8 hours 30 minutes QIAampÂ® DNA Micro extraction: 2 hours 30 minutes. Total Time Spent On Case At This Point: 22 hours. DNA Quantitation. The next step is to determine how much human DNA is present in the extracted samples.otal Time Spent on Case: 54 hours 15 minutes. Conclusion. Obviously, this time-line is a rough estimate of how long it would take to analyze a relatively straightforward case based on my experience in the laboratory. The total time adds up to approximately 54 hours and 15 minutes.
