Embryo test offers hope to parents Jun 19, 2006
PGD involves taking a single cell from an IVF embryo and delicately testing the minute quantities of Deoxyribonucleic acid (DNA) it contains for the presence of a known mutation for genetic disorders like cystic fibrosis. With PGH, a single cell is taken from the embryo and its entire genetic complement multiplied a millionfold before testing whether the embryo has inherited the defective gene from its father or mother.

Double-duty 'DNA' Jun 16, 2006
Chief Ramsey says he still relies on DNA in his police work, albeit today it stands for deoxyribonucleic acid, or the genetic material in humans. GRANDMA'S BOUNDARIES. (Townhall.com)
Inside the Beltway (John McCaslin) Jun 16, 2006
Double-duty 'DNA' D.C. Metropolitan Police Chief Charles H. Ramsey had to laugh when telling Inside the Beltway that he's been around law enforcement long enough -- three decades and counting -- that "when I used to write the letters DNA all over my police reports, it stood for Does Not Apply." Chief Ramsey says he still relies on DNA in his police work, albeit today it stands for deoxyribonucleic acid, or the genetic material in humans.

DNA Evidence Leaves No Doubt Jan 29, 2006
" DNA testing is based on the concept that every person has a unique genetic pattern found in DNA - deoxyribonucleic acid - which can be extracted from the smallest trace of blood, hair, saliva, semen, sweat or skin. Except for identical twins, every person has an individual DNA profile, so a sample matched to a specific person can help explain his or her whereabouts. If a burglar cuts himself breaking into a house and leaves behind a blood stain, forensic experts can use that DNA to link the... (Tampa Bay Online, FL -- News)
