Answer:
C. identification. PCR testing can aid in the identification of fly species in a forensic investigation.
Step-by-step explanation:
PCR testing can aid in the identification of fly species in a forensic investigation. PCR (Polymerase Chain Reaction) is a laboratory technique that allows the amplification of a small amount of DNA to detectable levels.
In forensic entomology, PCR can be used to identify the species of flies that are found at a crime scene. This is important because different species of flies have different developmental rates and life cycles. By identifying the species of fly present at a crime scene, forensic investigators can estimate the time of death more accurately.
PCR can be used to identify the fly species by analyzing the DNA present in the fly samples. The DNA is extracted from the samples and then amplified using PCR. The amplified DNA can then be sequenced to identify the fly species.
Therefore, the answer to the question is C. identification. PCR testing can aid in the identification of fly species in a forensic investigation.
