The coiled molecules of DNA in human cells carry a unique chemical code that can match a trace of blood, semen, skin or hair to the person who left it. DNA (deoxyribonucleic acid) carries its code in four characters denoted by the letters A,T, C, and G. But no microscope is powerful enough to see how this code is arranged on a given DNA molecule, so science must use more indirect methods to read it. Forensics laboratories use several different methods for determining whether two samples indeed carry identical stretches of code.

They seemed unlikely candidates to make one of the pivotal discoveries of the 20th century. Francis H.C. Crick was a 35-year-old Ph.D. candidate who had abandoned physics, hoping to find his niche in biology. James D. Watson was a gawky-looking 24-year-old who rarely bothered to tie his shoelaces. Both scientists were supposed to be working on other things, but they believed fervently that the most important scientific problem of their time was the mystery of inheritance - how everything from diseases to hair color to the very instructions to make a human being was passed on from generation to generation.

A man arrested recently in Puerto Rico for domestic offenses resembles the composite of the Fairmount Park rapist, city police said yesterday, adding that the suspect has lived in Philadelphia. As a result, the man, whose name was not released, has agreed to provide DNA that will be compared with evidence collected in the murder and rape of medical student Rebecca Park in Fairmount Park and the rape of another woman off Kelly Drive. The Fairmount Park assailant is also suspected of a third attack on the West River Drive in which the victim managed to fight off her attacker.

Do you have the feeling you're related to someone famous? Maybe it's an uncanny sense that Mozart was your ancestor. Or that Genghis Khan might be in your family tree. That affinity you feel for ancient Rome can't be an accident, can it? Touring the toppled ruins of columns and friezes in the ancient city stirs something in you. Perhaps one or your ancestors was one of those emperors, or perhaps just a Roman soldier. It's in your blood. Now, with a simple swab of your cheek and a few hundred dollars, you can find out. Commercial genetic genealogy is barely five years old, but already it is proving irresistible to many.

In a narrow ruling June 3, the U.S. Supreme Court declared that the DNA swabbing of people arrested in connection with serious crimes is legal. The Maryland attorney general praised DNA swabbing as the 21st-century equivalent of fingerprinting and said it would help solve crimes. No doubt. But the ruling represents yet another way our DNA is slipping beyond our control even as few standards exist for its use, storage, and destruction. The implications are laid out in Biotechnology in Our Lives , the latest book from the Council for Responsible Genetics, a Cambridge, Mass., nonprofit focused on the ethics of gene research and biotechnology.

In what officials say is the nation's first such countywide effort, Bucks County police departments announced Tuesday that they have created a database of DNA samples collected from accused or suspected criminals. The mouth swabs for the database are collected on a voluntary basis, with police requesting them from those who have been arrested or from suspects. The aim is to catch criminals who often fly under the radar of national and state DNA databases, which contain the genetic material of more hardened felons and sex offenders forced to submit DNA samples.

POLICE yesterday announced the arrest of a man who allegedly raped a 40-year-old woman outside the Linc during an Oct. 5, 2008, Eagles-Redskins game. "It was obviously a real challenge for us because of the number of people in and around that stadium," Special Victims Unit Capt. John Darby said yesterday. "It's almost like finding a needle in a haystack. " Police said they arrested Tiaghgee Daughtry, 22, who lives in Tunkhannock, Pa., near Scranton, on Wednesday, for allegedly raping the woman on a bus during the game.

No one really knows what happened to Phil Purcell's plane that day in September 1963 over Kontum, Vietnam. A relief pilot saw him turn his ancient B-26 back toward Da Nang. But he never arrived - plunging, instead, into the highlands below and vanishing beneath the oncoming tide of history. For three decades, as his bones and those of his crewmates moldered in Vietnam, as his children grew up and his wife remarried, the story of who he was lay locked in his body's DNA, like a song waiting to be heard.

Why do visions of war and hacked, stub-limbed civilians from Africa fail to move us as much as the images of civilians under attack in other parts of the world? I contend that we - whites, blacks and blends - are less moved by images from Africa because we've lost the emotional connection with the branch of the African human family tree. Geneticists recently have published results that say we all share the same DNA with slight variations based on traumas and the places we've passed through, via our ancestors.

For 41 years, the boy in the box has rested in his pauper's grave - unidentified, his murder unsolved. Yesterday, in a final attempt to find his killer, police removed him from his solitary grave in a potter's field in Northeast Philadelphia. They took his body to the medical examiner's office, where technicians will try to extract DNA from his remains. They hope such evidence will help identify him and eventually help nail his killer. "It's hard but it's been done before," said Lt. Ken Coluzzi, head of the special investigations unit at the police Homicide Division.

THE DAY AFTER her little sister's funeral, Crystal Smith searched the piles of condolence cards her family had received. She was desperate to find something from Christopher Bloomfield. She also reread the small notes that accompanied the flowers that had crowded the funeral home. She hoped one of the arrangements was from Bloomfield, to express his sorrow that Sabrina had died. "I prayed so hard that he would've found it in his heart to say he was sorry," says Smith. But there was nothing from Bloomfield, who was behind the wheel of a 2007 Acura last July 29 when it jumped a curb on a tight bend of Sandmeyer Lane, a well-known drag-racing strip in a Northeast Philly industrial park.

ONE DAY IN JULY, police in Bensalem, Bucks County, interrupted a burglary in progress and caught two suspects. Eleven days later and 10 miles north, someone threw a rock through a window to get into a Falls Township home and steal three handguns. In the past, investigators might have been hard-pressed to solve the second break-in, let alone link it to the first. But thanks to a new countywide, multijurisdictional DNA database, cops had cracked both cases within weeks, after finding DNA evidence at the Falls burglary that proved the Bensalem baddie was behind both crimes.

It's been three years since two masked gunmen shot and killed Nafis Armstead and wounded another man in East Mount Airy. And a year has gone by since 22-year-old Brian Tootle was found guilty of first-degree murder and sentenced to life without parole in the death of Armstead, 23. On Tuesday, a Philadelphia judge ordered Aka Jones, 24, to be tried after a prosecutor said Jones' DNA had been found on a discarded gun used in the shooting and his...

WHEN A MONSTER snatched her beautiful teenage daughter off the street, raped, beat and strangled her and then left her like trash in a vacant Kensington house, a homicide investigator warned 17-year-old Anjeanette Maldonado's mourning family that bringing her killer to justice could take time. "The first detective told me: 'You're going to have to wait. You have to be patient.' I thought he meant next week," Anjeanette's mother Paulette Smith, 59, said yesterday. Now, nearly 19 years after Anjeanette was murdered on her walk to school, Smith's long wait for justice has ended.

In 1944, before anyone knew what DNA looked like, a young graduate student sought to learn more about genetic mutations by irradiating 50,000 bacteria with ultraviolet light. Most of the cells in Evelyn M. Witkin's petri dishes died in the process. But four were somehow resistant, and her subsequent insights would prove fundamental in helping the world understand how living things protect themselves from radiation and DNA damage. On Tuesday, Witkin, 94, was honored with a prestigious Lasker award for her long career, the last decades of which took place at Rutgers University.

When Kareem Johnson killed Walter Smith outside a North Philadelphia nightclub, prosecutors said, he shot him at such close range that Smith's blood splashed onto Johnson's red Air Jordan baseball cap. That cap helped convict him. "That hat that was left at the scene in the middle of the street has Kareem Johnson's sweat on it and has Walter Smith's blood on it," Assistant District Attorney Michael Barry told jurors. "DNA is a witness. It is a silent, unflappable witness. " But he was wrong.

Officials from West Chester - both the university and the borough - are betting on something scientific to help ward off the divisions that have separated communities grappling with the resurgent issue of race. They are looking to DNA. In a new initiative called "One University, One Ancestry," the school will offer DNA testing to students, staff, faculty, and community members. They hope it will not only give participants insight into the origins of their ancestors, but awaken them to shared experiences and backgrounds revealed by a closer look at the gene pool.

For centuries, dog lovers have been asking their pooches to sit and stay. These days, more owners are adding: Who's your daddy? The increasing options to administer DNA tests for dogs (and to a lesser extent, cats) answers the call of curiosity, sure, but the tests that reveal your mutt's family tree also can help vets better diagnose disease and manage lifestyle issues like exercise, diet, and behavior problems. At the very least, the tests - now more accurate than the ones first introduced to consumers about eight years ago - allow owners to know how big the dog they adopted at six months likely will be at six years.

An expert medical panel has endorsed using a DNA test as an alternative, not just an add-on, to the venerable Pap smear for cervical cancer screening. But the American College of Obstetricians and Gynecologists, which had a representative on the panel, says the new screening approach is premature. The ob/guns' group continues to recommend either Pap smears or "co-testing" using the Pap and DNA tests. The DNA test, called cobas and made by Roche, detects two strains of the human papillomavirus (HPV)
