Forensic Science Module Essay

1. deoxyribonucleic acid or deoxyribonucleic acidulous refers to the molecules that carry our genetic information. deoxyribonucleic acid washbowl be found in blood, skin cells, tissues, muscles, bones, teeth, hair, and saliva. 2. Mitochondrial desoxyribonucleic acid is deoxyribonucleic acid that can be inherited from ones pay off and is found outside of the cell nucleus. 3. CODIS is a software program that contains the desoxyribonucleic acid profiles of convicted offenders, missing persons, offensive scene turn out, and other sources. CODIS works by attempting to fight the samples of deoxyribonucleic acid junior-graded on the thirteen distinct regions or loci within the nuclear desoxyribonucleic acid. 4. praising 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 described as the method in which DNA is studied, by employ an enzyme to cut DNA strands into different sections. Lim itations to this process overwhelm the fact that it requires a large sample of DNA and samples that carry dirt or mold ordinarily will non work good with this symbol of test.1. I look at DNA has had and continues to concord such(prenominal) an impact on forensic science because a DNA sample can help suppose out who was involved in a criminal offence and even who was the person who committed the discourtesy. 2. I believe some of the challenges that come with collecting DNA evidence could include the DNA sample potentialityly beseeming alter, by factors even if includes natural causes such as dirt, dust, and mold. Some ways that I could overcome 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 motley and matched so it is d ifferent. I would choose nuclear DNA to work with because it is more complex which means it is slight likely for any two people to have the same pattern while mitochondrial DNA has less(prenominal) variability from one to another. 4. If I had to hit the books DNA samples I would choose 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 winning with just even a small act of the DNA sample. 5. The experts testimony can be dismissed by questioning its credibility, education,
