Yes,Chemistry is helpful in criminology in many ways.Criminology is the study of crime,criminals and corrections.Criminalistics is the forensic science of analyzing and interpreting evidence using the natural sciences.Criminalists examine physical evidence to reconstruct a crime scene. Physical evidence can be saliva ,tears,semen ,a weapon, a piece of clothing, a bloodstain or drugs. Fingerprints, bullets and shoe impressions are some of the important clues that criminalists analyze to ascertain the crime.In this technique DNA will be isolated from blood stains,semen stains or hair roots and will be subjected to southern blotting and DNA hybridization with the help of specific DNA probes.

Since the 1980s, DNA techniques have begun to be applied to forensic cases. Any tissue from the body carrying DNA may be used to identify a person. Increasingly, innocent people have also been released from prison based on DNA evidence analyzed by criminologists. Blood is also often analyzed and can tell criminalists a lot about a crime.

Criminalists use their knowledge of chemistry to identify controlled substances in drugs and body fluids. A criminalist may be called to a drug lab where illegal drugs are produced to analyze what police have found.

In this technique there are many approaches available for the synthesis of genes.When the detailed structure of a gene is available,this gene can be synthesized by a purely chemical method for the synthesis of a gene.
