Forensic Science Module Essay

1. deoxyribonucleic acid or deoxyribonucleic acid refers to the molecules that carry our genetic information. deoxyribonucleic acid ignore be found in blood, skin cells, tissues, muscles, b bingles, teeth, hair, and saliva. 2. Mitochondrial DNA is DNA that can be inherited from stars mother and is found outside of the cell nucleus. 3. CODIS is a software program that contains the DNA profiles of convicted offenders, miss persons, crime scene evidence, and other sources. CODIS works by attempting to match the samples of DNA based on the xiii different regions or loci within the atomic DNA. 4. Complimentary base patterns are pairs that always pair up together. Complimentary base patters are so important because the four bases make up DNA 5. RFLP is describe as the method in which DNA is studied, by using an enzyme to cut DNA strands into different sections. Limitations to this play include the fact that it requires a large sample of DNA and samples that carry dirt or deflect u sually will not work good with this type of test.1. I believe DNA has had and continues to wee-wee such an impact on forensic science because a DNA sample can garter figure out who was involved in a crime and even who was the person who committed 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 drown 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 while 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 inwardness it is less likely for any two people to have the same pattern while mitoch ondrial DNA has less variability from one to another. 4. If I had to analyze DNA samples I would choose the polymerase chain response to analyze the DNA. PCR creates strands of DNA from teeny-weeny 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 just even a small piece of the DNA sample. 5. The experts testimony can be dismissed by question its credibility, education,
