Forensic Science Module Essay1. deoxyribonucleic acid or deoxyribonucleic acid refers to the molecules that carry our contagious information. deoxyribonucleic acid can be found in blood, skin cells, tissues, muscles, bones, teeth, hair, and saliva. 2. Mitochondrial DNA is DNA that can be inherited from ones mother and is found outside of the cell nucleus. 3. CODIS is a software programme that contains the DNA profiles of convicted offenders, missing somebodys, crime scene evidence, and other sources. CODIS works by attempting to match the archetypes of DNA ground on the thirteen different regions or loci within the nuclear DNA. 4. Complimentary base conditions are pairs that constantly pair up together. Complimentary base patters are so important because the four bases make up DNA 5. RFLP is described as the method in which DNA is studied, by using an enzyme to cut DNA strands into different sections. Limitations to this process include the fact that it requires a large sample of DNA and samples that carry turd or mold usually will not work good with this type of test.1. I imagine DNA has had and continues to have such an impact on forensic science because a DNA sample can help figure out who was involved in a crime and however 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 ship canal that I could overcome these potential challenges include trying to collect more than DNA samples that are not ruined or damaged you can also attempt to clean the DNA if possible.3. The difference in the midst of 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 postulate nuclear DNA to work with because it is more complex which means it is less likely 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 learn the polymerase chain reaction to analyze the DNA. PCR creates strands of DNA from small 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 pink-slipped by questioning its credibility, education,
