LIFE SCIENCE

Detailed explanation-1: -DNA evidence is far more reliable to eliminate a suspect rather than to pin the blame on that person. In other words, DNA evidence could reveal that suspect A might have committed the crime, but that suspect B could not have committed the crime.

Detailed explanation-2: -Inconclusive results can occur for many reasons: for example, the quality or quantity of DNA may be insufficient to produce inter-pretable results, or the evidentiary sample may contain a mixture of DNA from several individuals (e.g., a sample taken from a victim of a gang rape).

Detailed explanation-3: -DNA analysis has little to offer forensic science. DNA evidence is typically easy to find at a crime scene. Genes are the basic and fundamental part of heredity. Siblings will have the same nuclear DNA, but different mtDNA.

Detailed explanation-4: -Compared to fingerprinting or eyewitness testimony, which both have inherent flaws and inaccuracies, DNA evidence is a highly effective way to match a suspect to biological samples collected during a criminal investigation.
