Thesis Discussion DNA phenotyping serves to determine the physical attributes of a specific individual based off of genetic material that was left behind at a crime scene. By being able to determine physical traits such as hair color, eye color, height and skin pigmentation researchers can narrow in on the appearance of a person who committed a crime. This is crucial in forensic genetics who’s geneticists play a vital role in investigating crimes and in turn play a†¦show more content†¦Science is providing us the chance to change lives and save lives, outweighing the negatives that may result. Forensic DNA Phenotyping will make crime investigation increasingly more efficient due to it’s ability to determine certain attributes of the suspect. Instead of the police investigators searching for a suspect without any idea of who they should be searching for, through DNA phenotyping police can now have a narrower clue as to the appearance of the individual due to the ability to determ ine their faces morphology including hair color, eye color, skin pigmentation, gender, and height. Compared to current practice of racial profiling used by investigators following a crime, DNA phenotyping would eliminate this practice by providing and more detailed profile of who it is they should be searching for. Making forensic DNA phenotyping far more efficient and reliable then other methods. Also, the use of eye-witnesses who are not always accurate often lead to the conviction of an innocent individual. This can be prevented by forensic DNA phenotyping and eliminate the possibility of a wrong accusation by providing genetic basis for it’s claims. Though more phenotyping is in the works, currently sex, hair color, and iris color have been proven, along with being able to provide a detailed profile of an individual. Also, DNA phenotyping such as testing for a DNA match, or simply matching DNA/fingerprints to an individual should be used because the results are factShow M oreRelatedEssay on LHON: Mitochondrial Mutations and More853 Words   |  4 PagesMitochondria are small organelles found in eukaryotic cells which respire aerobically. They are responsible for generating energy from food to ‘power the cell’. They contain their own DNA, reproducing by dividing in 2. As they closely resemble bacteria, it gave the idea that they were derived from bacteria (which were engulfed by ancestors of the eukaryotes we know today). This idea has since been confirmed from further investigations, and it is now widely accepted.

Mitochondria are vital organelles, providing 90% of the body’s energy by producing adenosine triphosphate as well as playing an integral part in the cell’s ability to form new deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) molecules by powering metabolic pathways. Mitochondrial DNA is a small portion of our genome (37 genes out of the 20 000-25 000 that make up our genome are mitochondrial DNA)Read MoreMitochondrial Neurogastrointestinal Encephalopathy Disease ( Mngie )1461 Words   |  6 PagesBiology 1December 2016 Mitochondrial Neurogastrointestinal Encephalopathy Mitochondrial Neurogastrointestinal Encephalopathy disease (MNGIE) is an extremely rare disease that affects the process of muscles and shows up in equal numbers of men and women. Only 70 cases of this disease have been reported. A mutation of the thymidine phosphorylase causes MNGIE and lowers the production of adenosine triphosphate production. To begin, mitochondrial neurogastrointestinalRead MoreThe Crime Scene Of A Virginia Man999 Words   |  4 Pagesforms of evidence have been allowed in court in many cases and have also convicted many innocent people.

Mitochondria, dubbed the ‘powerhouse of the cell’, are a type of organelle present in most human cells. Their primary function is to generate Adenosine Triphosphate (ATP), the cell’s principal source of chemical energy. Unlike most other organelles, mitochondria store their own set of genetic material, distinct from the DNA situated in a cell’s nucleus.

Literate Review Since the discovery of the structure of DNA, the world has made many advancements in science, such as DNA sequencing, gene therapy, and genetic engineering. Genetic Engineering (GE) refers to the direct manipulation of organism DNA to alter an organism s specific characteristic in a way for beneficial use (Nester, 2014).
