DNA Finger Printing

Length: 3 Pages 696 Words

In this report, I have chosen the area of DNA profiling as my biotechnology assignment. Firstly I will describe the structure of DNA, how it works and the process of manipulation it takes. There are many areas where DNA is being manipulated for different purposes to enhance human development, genetic disorders, saving endangered species, DNA profiling. The DNA molecule is a double helix, resembling a spiral ladder. The sides of the ladder are made up by alternating units of phosphate and a sugar, deoxyribose. Attached to the sugar units are the rungs of the ladder, which are made up of combinations of bases. There are four bases: adenine, guanine, cytosine and thymine (A, G, C, T). Each rung in the ladder consists of two bases. Because of chemical attractions, only a few combinations of bases are possible: A combines with T and C combines with G. The information contained in DNA is determined primarily by the sequence of letters along the ladder. Living organisms that look different or that have different characteris Continue...

Unlike the fingertips that can be altered by surgery, a DNA fingerprint is the same for every cell tissue an organ for a person. Like the fingerprints each person has a unique DNA fingerprint. Each probe typically sticks in only one or two specific places on the nylon sheet. 3: Transfer of DNA to nylon:The distribution of DNA pieces is transferred to a nylon sheet by placing the sheet on the gel and soaking them overnight. There are over 100 different restriction enzymes that we know of, and each one cuts a different area of DNA. tics also have different DNA sequences. DNA fingerprints are useful in several applications of human health care research - diagnosing inherited disorders and preventing them; such as cystic fibroses, hemophilia, Huntington"tms disease, familial Alzheimer"tms, sickle cell anemia and many others. To conclude my report on DNA profiling, I believe that the use of DNA manipulation is to the benefit of the human race and I think it will continue to establish itself in society as an efficient way of profiling and in other forms of manipulation it will continue to help the human development into the future, but certain morals and boundaries should be watched because every revolutionary invention should work for the society but not against it. Special enzymes called restriction enzymes are used to cut the DNA at specific places. N),it is seen as one of the new enumeration and registration technology and using the Bible (1 Chronicles 21:1-30), they think this is a new numbering of God's people and according to 1 Chronicles God opposes this process. It resembles the bar codes used by grocery scanners. 6: DNA fingerprint:The final DNA finger print is built by using several probes 5 to 10 more simultaneously. Only a small amount of tissue - like blood, hair, or skin - is needed.
