DNA Fingerprinting
The deoxyribonucleic acid (DNA) composition of a human determines hair color, eye color, skin color, and any other physical or behavioral traits exhibited. DNA has a specific pattern that is called a DNA fingerprint. The chance that two people would have the same DNA fingerprint is one in thirty billion (except in cases of identical twins) (Mosby 1998). Since it is incredibly rare that two people do have an identical DNA pattern, there are many uses for the DNA Fingerprint. This paper will give a brief summary of what DNA fingerprinting is. It will tell its uses for today as well as how it will be used in the future. It will also discuss the advantages and disadvantages of using DNA fingerprints. An abstract look at characteristics passed down by the parent and how inherited characteristics are linked to DNA fingerprints. Finally, an experiment with Drosophilia Melonogaster will be discussed. Every human cell (except gametes) contains a set of 23 chromosomes. Inside the chromosome is a coiled mass of genetic material called DNA. The structure of DNA looks like a twisted ladder with rungs. The four nitrogen bases that make up DNA are adenine, thymine, guanine, and cytosine (A, T, G, C) which are the rungs of the ladder.
For example, learning about an illness from a prenatal baby can help prepare the families of the future diseases. The police and the media pointed the finger at the former football player O. The labeled probe is added to the block filter in buffer and incubated for several hours to allow the probe molecules to find the DNA targets. By using this method, they simulated a genetic chain of events occurring when a person is exposed to the tobacco smoke. By fingerprinting the parents, before they have the baby it can prepare them for the risks of having a sick child ahead of time. The fingerprint showed significant genetic heterogeneity among the strains (Harold 2000). The investigation of Linda's murder turned out to be unsolvable, until July 31, 1986 when another young girl named Dawn Ashworth was also murdered and raped much like Linda was. It also will give scientists a better understanding of their habits when they were alive. To protect the integrity of the sample, chain of custody (any person having control of the sample or access to the sample is documented), is strictly maintained. This record will help aid in criminal investigations. They used a method called DNA damage fingerprinting. Cloning is used to make an exact replica of a gene in an individual.
