Thus there is deoxyribose on both sides of phosphate. The importance of DNA evidence in the Twin Towers attacks cannot be overstated; because many of the victims were rendered unidentifiable otherwise, the use of DNA to establish the identities of these individuals is considered extremely important.
The sugar puckering is C: Although DNA identification techniques continue to be refined and improved, it is unlikely that all of the identities of all of the victims of the September 11, attacks will ever be completely known. In this regard, Harlan notes that law enforcement authorities have come to heavily rely on genetic information as a central element of their investigative and prosecutorial responsibilities.
The pitch is 3. Depending upon the nucleotide base per turn of the helix, pitch of the helix, tilt of the base pair and humidity of the sample, the DNA can be observed in four different forms namely, A, B, C and D.
The helix is narrower and more elongated than A form. Obviously, intact bodies will require fewer DNA tests than fragmented remains, although decomposing bodies may not easily yield full profiles" p.
For example, on December 31,the New York Times published the final daily portraits the paper had been printing since September 15, ; the close of that fateful year also witnessed the final installment of "A Nation Challenged," a special section devoted to coverage of the "War against Terror" in which the portraits had appeared.
The number of bases is The number of base is 10 per turn of helix. The aftermath of the terrorist attacks on the Twin Towers. The helix is shorter and wider than B form.
According to Greenburg"The stand-alone section was deemed no longer necessary because the traumatic effects of September 11 had been woven into all aspects of national and international life.
After an individual is positively identified, though, law enforcement authorities may retain possession of the DNA samples even provided by those who were exonerated by the DNA identification Harlan, Indeed, September 11, now represents a demarcation point in American history, and it is reasonable to assume that people generations from now will continue to describe events in terms of their being "pre-" or "post-" September To date, approximately 1, victims of the Twin Towers attacks have been successfully identified using DNA identification techniques Gonzalez et al.
The base pairing is nearly perpendicular to helix axis. The importance of being able to identify a lost loved one was made clear in this essay. In most cases, such evidence protection requires an evidence custodian and a stipulation concerning how long evidence must be preserved, as well as formal procedures that must be followed prior to the destruction of old evidence in closed criminal cases Jones, The number of bases is 12 per turn of helix.
In RNA, the pyrimidine base thymine is replace by uracil. The helix is narrower and more elongated than A or B form.
Adenine will always pair with thymine and guanine with cytosine. The DNA backbone is a polymer with an alternating sugar-phosphate sequence.The Pros and Cons of DNA Fingerprinting - DNA fingerprinting is one of the greatest identification systems we have to-date to recognize an individual or living organism.
DNA analysis has a number of advantages over other identification methods and is a critical tool in associating severely fragmented remains, such as those that resulted from the World Trade Center (WTC) attacks, with victims.
DNA profile is considered as valid evidence in the court of law for paternity disputes and human identification.
Standardization of DNA extraction technique will improve the reliability and speed up sample processing time. If you are the original writer of this essay and no longer wish to have the essay published on the UK Essays website.
The DNA Identification System does have its benefits, as it would help in the medical department.
If you were rushed to hospital from a car accident and you are unconscious the doctor will know if you were allergic to the anaesthetic or if you were a private patient or not.
