What unique properties of the genome do forensic scientists use to generate a DNA footprint and
this footprint enough to identify a specific (one) suspect?
Solution
only one tenth of a single percent of DNA differs from one person to another, forensic scientist
use these variable regions to generate a DNA profile of an individual using samples from blood ,
hair ,etc.
scientist find markers in a DNA sample by designing a small pieces of DNA(probes) that will
bind to a complementary DNA sequence in the sample.A series of probes bound to a DNA
sample creates a distinctive pattern for individual.scientist compare these DNA profile to
determine whether the suspect\'s sample matches the evidence sample.if they don\'t match the
person don\'t contribute to the crime scene.If it match it means the suspect may have contributes
to the evidence sample.
There are variable number of tendom repeats which are used to identify the suspects, which vary
in each person.
RFLP(restriction fragment length polymorphism ) is a technique used in this concern as it
analyze variable length of DNA fragments that results from digesting a DNA sample with a
special kind of enzyme.
various other techniques are also there as- PCR,STAR analysis.
