Dna Evidence Of A Dna Unit Within A Crime Lab - 1551 Words

Today in the crime world, DNA evidence is strongly accepted in solving crime cases. This is all based in part by allowing a crime laboratory to have a designated unit whose main goal is to analyze DNA evidence to aid investigators with positive outcomes in crime case solving. With that being said we are going to discuss the functions of a DNA unit within a crime lab as well as address the vital role these units play in solving crime. Let’s start by defining what in fact is DNA analysis. According to the FBI’s crime lab, the DNA analysis process can take place when bodily fluid stains and other biological tissues are found on physical evidence collected from a crime scene (FBI DNA Casework Unit, 2016). The DNA testing results obtained from evidence samples are compared to DNA from reference samples collected from known individuals. Such analyses may be able to associate victims and suspects with each other, with evidence items, or with a crime scene (FBI DNA Casework Unit, 2016). The FBI and other national crime labs can conduct nuclear, Y-chromosome, and or mitochondrial DNA testing depending on the technology and funds appropriated to the unit. Smaller fielded units would probably not be able to do some testing which would result in them forwarding evidence or using other assets with greater capabilities. DNA is the genetic material that makes up the characteristics of all living organisms. While all human DNA is very similar in nature, there is just enough differences inShow MoreRelatedThe Louisiana State Police Crime Laboratory1045 Words   |  5 PagesThe Louisiana State Police Crime Laboratory was developed to provide the highest quality of professional forensic services to the State of Louisiana. The commitment of the agency includes applying sound scientific principles in all analyses, being responsive to our customers, conducting our operations in a fair and objective manner, and being a leader in advancing forensic science. The mission of the laboratory is to assist all of the local, state, and federal law enforcement agencies in LouisianaRead MoreDNA in Forensics Essays785 Words   |  4 PagesThe origins of DNA were first discovered during 1857 by Gregor Mendel the Father of Genetics†, whom was performing an experiment of genetics with pea plants, and would provide a basic foundation towards DNA and Genetics. Friedrich Miescher and Richard Altmann in 1869 were also part of the first people to discover DNA. While testing some sperm of a salmon, they discover a strange substance that they would name as nuclein, which is known as DNA. This new form of nuclein (DNA) would be found toRead MoreWhat physical evidence does in a criminal trial and the vast impact it can make1678 Words   |  7 Pagesand justice lies within cases that include physical evidence. Physical evidence, whether fibers, fingerprints, or DNA, can give a jury proof beyond a reasonable doubt. Physical evidence can convict a criminal, or it can free an innocent man. It can bring closure to families and to the law enforcement that work the cases. The following cases will show what physical evidence does in a criminal trial and the vast impact it can make. For each case I will examine how the physical evidence was important toRead MoreCrime Scene Analysis: Personal Experience1537 W ords   |  7 Pages Unit 9 Unit 9 Assignment CJ328-01: Forensic Fingerprint Analysis Kaplan University Abstract Little is known about the decision-making processes of homicide detectives or crime scene investigators.

DNA profiles are encrypted sets of numbers that reflect a persons DNA makeup, which can also be used as the persons identifier. DNA profiling should not be confused with full genome sequencing. It is used in, for example, parental testing and rape investigationRead MoreImportance Of Forensic Chemistry1647 Words   |  7 Pagesincluding Forensic Files, CSI, and Bones. Forensic chemistry is important because without it we wouldn’t know the outcome of a crime. The forensic chemist’s job is to examine evidence given to them from a crime scene, when it happened, and even who committed the crime at times. Forensic chemistry deals with the chemical analysis of a variety of types of physical evidence.
