Soru 1
DNA profiling is universally accepted as the highest
standard for identification in forensics, and it has been used
successfully for decades to convict or acquit suspects. In
fact, a 2009 National Research Council report on forensic
science eviscerated all other identification techniques,
from fingerprinting to bite mark analysis, holding DNA as
uniquely capable of reliably distinguishing between any
two people on Earth. But DNA also has limitations. It can
degrade and be difficult to extract from trace evidence,
such as skin and hair. So Glendon Parker, a biochemist
at the University of California, has been studying unique
markers in the proteins made by DNA. “The major
advantage is that protein, particularly hair protein, is more
stable than DNA,” he explains.
It is understood from the passage that DNA profiling- - - -.
A
is used both to accuse someone and to find someone
innocent
B
became a more successful method after 2009
C
began to be used universally after the report in 2009
D
gained a scientific value after it began to be used in
forensics
E
is a method that has been used since ancient times
