Mary-Claire King Case Analysis

1238 Words | 5 Pages

By the time of its application in the U.S. military in 1991, mtDNA identification had been used in some international and domestic atrocities and murder cases. The most famous application is Mary-Claire King’s task in the late 1980s in identifying the victims of the Argentine “dirty war” at the request of the Mothers of Plaza de Mayo, an organization sharing many features with the NLF. In 1991, mtDNA saw its first use in the U.S. Mark Stoneking used the mtDNA from a skull to identify a girl lost for four years. An mtDNA test to trace the fate of Tsar Nicholas II’s families was also proposed in 1991. Encouraged by the success, on July 15, 1991, two AFDIL experts collected seven bone fragments in the coffin supposed to contain Maj.

The two story traditional Victorian house exploded and engulfed in flames to eliminate evidence. After the charred bodies were recovered from the fire, tissue samples were obtained to identify each victim, using DNA, which is the molecule responsible for transmitting all hereditary information passed on from one generation to the next (Johll pg. 409, 2007). To determine the cause of death, an autopsy was performed and tissue samples from each victim. Among the evidence recovered after the fire was a single syringe, which was fully intact and sent for analysis.

CILHI Summary

1623 Words | 7 Pages

A DNA molecule is composed of two complementary chains of four different types of nucleotides. Although more than 99.9% length of the human DNA (nucleotide) sequence is shared by all individuals, the remaining one thousandth is highly variable and specific to each person. As long as DNA molecules can be extracted from a single piece of bone, then amplified to an amount enough to sequence them, the bone will be sufficient to figure out the identity information unique to few individuals within a large population, sometimes to a single person. Because of this technology, the judgment of a soldier’s death will not need statures estimation from lengths of limbs, age prediction with pelvic bones, dental comparison, but just an alignment of a string of letter code (nucleotide sequence in a DNA) obtained from his bones with those from his relatives (conventional methods still play supportive roles as a single type of DNA identification alone is insufficient to determine one soldier’s identity). A person’s identity is not just his height, sex, race, and age, but a long array of A, T, C, G (four types of

Essay On Tutankhamun's Death

1303 Words | 6 Pages

Other experts, however, rejected the hypothesis of homozygous sickle cell disease based on survival beyond the age of 5 and the location of the osteonecrosis, which is characteristic of Freiberg-Kohler syndrome rather than sickle cell disease. Research conducted in 2005 by archaeologists, radiologists, and geneticists, who performed CT scans on the mummy found that he was not killed by a blow to the head, as previously thought. New CT images discovered congenital flaws, which are more common among the children of incest. Siblings are more likely to pass on twin copies of harmful genes, which is why children of incest more commonly manifest genetic defects. It is suspected he also had a partially cleft palate, another congenital

King Tut's Family Mystery Summary

104 Words | 1 Pages

According to Zohi Hawass’ article on King Tut’s Family Secrets, mummies lead archaeologists and scholars to contradicting feelings about whether they should be studied or not. Inspecting Tutankhamun’s body, artifacts and two fetuses found in the tomb drove archaeologists to pose questions needing answers. CT scan assisted in determining that Tutankhamun was nineteen years old when dying, had a broken leg, and skull’s hole. Moreover, using DNA analysis displayed Tutankhamun’s clubbed foot, missing toe’s bone, and disease’s pathogen. Both CT scan and DNA analysis helped archaeologists discover Tutankhamun’s complex family relationship and how his family sibling marriage led them to suffer from genetic diseases.
