...wanting to test the forces of nature a second time, I invited the tube into my room. I poured him a drink and opened a full tube of lip balm. I sliced the top quarter of stick off the new tube and forced it down the neck of my annoying guest...
Besides sickness or injury, students can be excused from examinations in times of family emergencies. In such cases, if time permits, the student can take the test in absentia, said Dean of the College L. Fred Jewett...
...Midlands case, Jeffreys established that the DNA pattern of the 17- year-old suspect did not match those obtained during the murder investigations. The patterns of each of the 2,000 Midlands men will undergo similar scrutiny. But that may take a while. Each test involves a complicated series of steps over a period of 2 1/2 weeks. Still, Jeffreys believes, with further refinements, and despite the $300 price tag, the test will more than pay for itself not only in criminal investigations but in the resolution of paternity suits. Says he: "The system works beyond my wildest dreams...
...could they be so sure? By using the new technique of DNA fingerprinting, which involves analyzing nuclear rather than mitochondrial DNA, they had proved that while the same person had committed the murders, the man in custody was not the culprit. This month the police began using the test on blood samples from 2,000 Midlands men, hoping that if one of them is guilty, his DNA print will give him away...
...test involves comparing the DNA of blood, semen or hair roots found at the scene with the DNA of a suspect. What makes it virtually foolproof is that no two people (other than identical twins) have the same genetic characteristics. While considering this fact in 1983, Alec Jeffreys, a geneticist at the University of Leicester in England, realized it might be the basis for an important new tool in criminal investigations. Using restriction enzymes as "scissors," he cut the DNA taken from several people into segments and arranged them into patterns that somewhat resemble the bar codes found on supermarket...
