LGC Forensics, on a former RAF base in deepest Oxfordshire. (This lab deals mainly in chemical and biological traces, and DNA. Half a dozen others across the UK do marks and tracks, drugs, forensic pathology, firearms and digital forensics.)
The company is Britain’s largest single supplier of outsourced forensic science services. It was scientists from LGC Forensics—it employs 675 of them, 225 on this site—who found the evidence that helped convict the killers of Joanna Yeates, Damilola Taylor, Milly Dowler, Vikki Thompson, Rachel Nickell and, most recently and famously, Stephen Lawrence.
For a much-hyped, very modern science that has advanced at breakneck speed since the discovery of genetic fingerprinting by Sir Alec Jeffreys in the mid-1980s and the launch, barely a decade later, of the world’s first national DNA database by Britain’s soon-to-be-defunct Forensic Science Service or FSS, DNA forensics still relies, above all, on painstaking process.
There’s little glamour here, and a lot of methodical, meticulous,
minute
and above all time-consuming graft. Exhibits come in and are logged. Depending on the nature of case and evidence, an appropriate reporter, the senior scientist on the investigation, is allocated.
"The reporter liaises with the police, establishes what has to be looked for, draws up a strategy," Sheriff explains. "They instruct the forensic examiners, review and interpret what they find. And it’s the reporter who stands up in court."
Rigour, continuity, integrity of procedure are all. Everything is recorded: who handles material, where it’s come from, what they do to it, what they find, where it goes next. Stray DNA, any risk of contamination, must be minimised: hence the protective clothing (junked after every session), the brown paper (bagged for eventual debris), the company DNA database that allows any staff DNA found to be swiftly discounted.
Because the thing about DNA evidence, strong as it is, large as it looms in the public’s imagination, is that it connects a human and an object. It doesn’t prove when the two came into contact. Nor does it necessarily prove they were actually in direct contact at all.
"It’s not just the finding of the evidence," says Ros Hammond, a senior scientific adviser who has worked on many high-profile cases. "It’s how did it get there, and can we rule out any other way it did so? And what does it mean?"
You have to be careful, analytical, determined, patient and—as five experts relate, in relation to six major cases—occasionally inspired.
From The Guardian, January 17, 2012 [br] What is the function of LGC Forensics according to the passage?
选项
A、convict killers
B、deal with DNA
C、analyze cases
D、stand up in court
答案
B
解析
本题为细节题。文章第一段提到“This lab deals mainly in chemical and biological traces,and DNA.”意为:这个实验室主要处理化学、生物遗留物和DNA,所以选项B正确。
