Soil

Soil is the upper layer of the ground comprising of a mixture of sand, silt, clay, loose rock fragments, and organic matter that can support the growth of rooted plants. The relative proportions of sand, silt and clay determine the texture and size of the pores of the soil, which affects its ability to allow air and water to penetrate/infiltrate.

Investigator Sheer is testifying about DNA evidence she found at the crime scene that matches the suspect on trial. The prosecut

Ratling [72]

She will give the DNA fingerprinting report to the jury which will have samples of suspect and its profile matching to the evidence found at the scene of crime.

In DNA fingerprinting hair, blood, semen, or other biological samples are required for the comparison of suspect and evidence. It depends on the unique polymorphism in their DNA.
The fragments of DNA are made to run on the electrophoresis gel and the similar bands observed will confirm the matching.
The DNA fingerprinting will provide very exact evidence if the DNA samples matched.
