P RINCE has an heir. According to the heir. We've been waiting for this to happen since the purple music icon died without a clear line of inheritance. Nature abhors a vaccum, and here to fill that vacuum is 39-year-old Carlin Q. Williams , of Kansas City, Mo. He's a Colorado prison inmate who has filed a paternity claim with a Minnesota court against the Prince estate and is seeking DNA testing to determine if Prince is his biological father. In an accompanying affidavit, his mom, Marsha Henson , contends that she conceived Williams while having sex with Prince at a Kansas City hotel in July of 1976.

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.

Third in a series. Read part one and part two here. The secret to having a long life, a doctor once told me, is choosing your parents very carefully. He wasn't kidding. Diet? Of course. Exercise? Who doesn't know that? Avoid stress? Well, duh. Don't smoke? Well, double duh. But for a gold-plated pass through the Pearly Gates, nothing beats having a flourishing family tree whose roots, generation after generation, are flush with a robust DNA that is passed faithfully along.

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.

The prosecution alleges that the killer of Cheryl Hanible in 1989 left behind "touch" DNA when he removed the lace from one of her sneakers and used it to strangle her. And that DNA, Philadelphia police DNA analyst Bryne Strother testified Wednesday, almost certainly came from 54-year-old Rudolph Churchill of Paulsboro. But could Churchill's DNA have somehow, accidentally, been picked up by Hanible's sneaker without his ever touching it? That was the hypothetical question posed by defense attorney Gina Capuano in questioning Strother during Churchill's Common Pleas Court trial on rape and murder charges in the stranglings of Hanible and Ruby Ellis.

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.
