Five years later, in Romulus, Michigan, a flight attendant was raped and murdered. Again, authorities were unable to locate any suspects (Adams)
One of the most noted impediments to this goal, he notes, is the limited law enforcement training and education on how to properly identify, preserve and collect biological evidence that may contain a DNA profile of the perpetrator. Limited training resources, coupled with ever-changing technology, "results in a failure to take full advantage of the power of DNA" (Asplen)
Both Philadelphia, Pennsylvania and Fort Collins, Colorado authorities used DNA evidence, in 2002, to solve a series of rapes and a murder that had been perpetrated by the same individual. DNA evidence also provided the breakthrough authorities needed to solve the 'Green River' killings that had been unsolved for years and had previously cost $15 million for the investigation (Coble)
For this reason, judges must have a solid grounding in scientific method, which traditionally they do not. Binnie expressed the need for a scientific literacy across the legal profession (Cosh)
It took nine months for the DNA results to exonerate Mr. Holder (Ferrara)
Certainly there are challenges, as there is with the implementation of any radically new technology, especially one that is still advancing. However, DNA technology is the pest investigative tool to be introduced to law enforcement since the advent of fingerprinting (Hansen)
"By mid-1999 more than 60 people had been released from American prisons following post-conviction analysis of DNA evidence. Many of them had already served a number of years behind bars" (Langeneckert)
These enzymes cut the DNA only at specific cutting sites. It is this pattern of cutting sites that is inherited from one's parents and is the beginning of the creation of a genetic profile (Levine)
The Innocence Project these exonerations included 12 people who had been on death row. In addition, the Innocence Project was counsel for these appeals in 65% of these cases (Nowak)
These included $755 million to clear up the backlog of approximately 400,000 samples and other evidence in rape case, in an effort to track down assailants. $500 million of this money will also be used to "help crime labs conduct DNA analysis, educate examiners and assist forensic analysis programs" (Posner)
The DNA evidence collected from the crime scene needs to still be in good condition, which is not always the case. In many instances, either the testing was requested by the convict or it was solicited by the state in conjunction with a broader program (Lithwick, 2012)
In Virginia, a program has been run for years, and while there are criticisms about the cost, it has led to exonerations, even during the phase of random testing. Today, there is a move to allow for DNA testing if not during the investigation then certainly at the point of conviction (Mears, 2013)
The ACLU (2011) has stated that 17 people on death row were exonerated as of September, 2011. A project in Virginia found 33 individuals convicted of sexual assaults who between 1973-1987 who were still incarcerated in 2012 and whose innocence was demonstrated by DNA testing (Michaels, 2012)
Meanwhile, DNA evidence has proven that a security guard in Mexico, Blas Delgado Fajardo, was not the man who slashed the throats of a couple from Toronto (Song, 2006). And there are many, many stories of convicted killers and rapists being freed because new DNA technologies prove they were innocent; two men in New York, Alan Newton and Scott Fapiano, spent more than 40 years in prison for sexual assaults they didn't commit, according to WNYC, New York Public Radio (Mogul, 2006)

In animals, only 5% of the cases were successful and in the remaining cases the dead animal child were born. (Agarwal, 2010) Apart from fatalities the some other issues such as premature aging, weakening of the immune systems and sudden deaths have also been reported in a number of cloned mammals
This technique is very fast and through it about one hundred and fifty copies of an array consisting of twelve thousand genes can be made only in one day. (Asbury, 2005) The second advantage of DNA microarrays is that it is less expensive when compared to other techniques of the same kind
But people and the researchers were horrified by the fact that if a mammal can be cloned then it is quite possible that a human being can be cloned as well. (Brock, 2009) Advantages of Cloning Human cloning would enable the women who do not have an ovary and men who do not have a sperm to have a child who would be their own
This information also enables the people to logically analyze different inventions and advancements in biology so that they can decide that whether the projected discovery is good for them or not. (Silva, 2008) In the past years, a number of discoveries have been made in the field of biology including, DNA discoveries, genetic engineering, molecular biology, biotechnology, biodiversity, cloning, etc
It is projected that in the future, genetic engineering is going to be a major part of our lives and its various aspects can either be an advantage or a disadvantage for us and for the entire world as well. (Surhan, 2002) Advantages of Genetic Engineering Through the advancements in the field of genetic engineering, the researchers are now able to develop new and advanced medicines that are of great importance for the health of the people
