Police forensic services frequently use biotechnology as a tool to investigate crimes. Agents of the forensic department of NYPD found a couple of hairs near the victim. Describe the actions that the NYPD Department will take to find the culprit, knowing they already have three suspects. APA Format 300 words Include in-text citations from book: Gerard J.

The NYPD forensic department will utilize advanced biotechnological techniques, specifically DNA analysis, to identify the culprit from the hair evidence collected near the victim. The process begins with the collection and preservation of the hair samples to prevent contamination. These samples will then be subjected to DNA extraction procedures, which isolate genetic material from the hair's root or follicle tissue (Tortora, Funke, & Case, 2019). If the hair lacks a follicle, mitochondrial DNA analysis can be employed, as it is maternally inherited and can still provide valuable forensic information from the shaft.

Next, the extracted DNA will be amplified using polymerase chain reaction (PCR) to generate sufficient genetic material for analysis. This process involves targeting specific regions of the DNA known as loci, which vary among individuals, enabling the creation of a DNA profile. The resulting DNA profile will then be compared to the DNA samples obtained from the three suspects, which were previously collected and stored in a forensic DNA database (Tortora et al., 2019). A match between the DNA profile from the hair and one of the suspects' profiles would provide strong evidence linking that individual to the crime scene.

Furthermore, the forensic team may employ additional biotechnological tools such as mitochondrial DNA analysis if nuclear DNA is degraded. The final step involves compiling and analyzing the DNA evidence to determine statistical probability and strength of association with the suspects. Through this process, biotechnology allows the NYPD to reliably identify or exclude suspects, thereby aiding the investigative process with scientific precision (Tortora et al., 2019).

In conclusion, DNA analysis remains a cornerstone of forensic investigations, providing definitive evidence in criminal cases through biotechnological methods.
