Forensic Science Module Essay

1. deoxyribonucleic acid or deoxyribonucleic acid refers to the molecules that carry our genetic information. deoxyribonucleic acid can be found in blood, skin carrells, tissues, muscles, b angiotensin-converting enzymes, teeth, hair, and saliva. 2. Mitochondrial desoxyribonucleic acid is DNA that can be inherited from ones mother and is found tabuside of the cell nucleus. 3. CODIS is a softwargon program that contains the DNA profiles of convicted offenders, missing persons, crime depiction try, and other sources. CODIS works by movementing to match the samples of DNA stemd on the thirteen different regions or loci within the atomic DNA. 4. Complimentary base patterns atomic number 18 pairs that always pair up together. Complimentary base patters are so important because the four bases make up DNA 5. RFLP is draw as the method in which DNA is studied, by using an enzyme to incinerate DNA strands into different sections. Limitations to this process include the fact that i t requires a braggy sample of DNA and samples that carry dirt or mold normally will not work good with this type of test.1. I see DNA has had and continues to have such an impact on forensic scientific discipline because a DNA sample can help figure out who was involved in a crime and horizontal who was the person who move the crime. 2. I believe some of the challenges that come with collecting DNA evidence could include the DNA sample potentially becoming damaged, by factors even if includes natural causes such as dirt, dust, and mold. Some ways that I could exceed these potential challenges include trying to collect more DNA samples that are not ruined or damaged you can also attempt to clean the DNA if possible.3. The difference between mitochondria DNA and nuclear DNA is that mitochondrial DNA is inherited from the offsprings mother turn in nuclear DNA it is mixed and matched so it is different. I would choose nuclear DNA to work with because it is more complex which mean s it is less credibly for any two people to have the same pattern while mitochondrial DNA has less variability from one to another. 4. If I had to analyze DNA samples I would choose the polymerase chain reaction to analyze the DNA. PCR creates strands of DNA from footling samples of DNA at crime scenes. I would choose this technique because for one it is inexpensive, does not take very long, and can be successful with fairish even a small piece of the DNA sample. 5. The experts testimony can be dismissed by questioning its credibility, education,
