Lesly Rodriguez Biology January 23, 2018 DNA is a long skinny molecule made up of nucleotides; the nucleotides consists of adenine, thymine, cytosine, and guanine. DNA also carries genetic information in cells and some viruses which forms two long lines of nucleotides twisted like a zipper known as the double helix. DNA can be extracted and kept in a database from having samples such as hair, saliva, fingertips, etc; the purpose of keeping it in a database is in order to secure vital information of an individual’s privacy and use it for an important event. The city of Chicago should make it mandatory for individuals and newborn babies to submit their DNA into a database. I foresee this due to solving crime efficiently, knowing circumstances that are from relatives, and the scientific method cures for the circumstances. …show more content…

According to Yourgenome, “DNA database is useful for police investigation crimes.” This quote supports why it should be mandatory to submit DNA into a database because if people were to do that, then the DNA can help police identify a suspect quickly and it can be strong evidence to show if an individual is guilty. Along with DNA and crime, the Justice of Department states “DNA can be used to clear suspects and exonerate persons mistakenly accused or convicted of crimes.” The previous evidence supports the argument to have DNA into a database due to how it can be very accurate because of the biological evidence that exists; and it would bring good faith in the criminal justice

It is a great technological innovation that can help bring evidences and fact faster. In the article The DNA Wars Are Over, “Forensic use of DNA technology in criminal cases began in 1986… In one of the first uses of DNA in a criminal case in the United States, in November 1987.” Sadly in 1985, DNA testing was not popular in the U.S. investigation and was not available in Cole’s case. I believe the U.S. court system is improving and yes there are a lot mistrials and wrongful conviction cases, but you cannot avoid the fact that DNA testing can bring better truth than just relying on statements of both

Why Is Gary Ridgway Called The Green River Killer?

657 Words | 3 Pages

Without the help of DNA, connecting offenders to their victims and the scene of the crime, so many cases would be left unsolved. Shockingly enough, it wasn’t until 1984 where DNA was used for biological identification. Once DNA started to play such a big role in criminal justice, many cases where they didn’t have enough evidence to prosecute, were brought to court and finally solved. Even though there was such a large gap in when the offenses were first committed and when they were solved, there was still justice for the victims and their families. An important case where DNA changes everything would be that of Gary Ridgway, otherwise known as the green river killer.

Analysis Of The Supreme Court Case Of Maryland V. King

980 Words | 4 Pages

For example, Maryland believed that DNA analysis helps to identify suspects more accurately and reduce future crimes, which would boost the public's confidence in law enforcement. The State even claimed that without the DNA Collection Act, which enabled the police to cheek swab from King, they would not have connected King to the sexual assault that he was ultimately accused of. Nevertheless, there is a risk in allowing Maryland to enforce its DNA Act for the purpose of only removing violent offenders. King actually acknowledges that DNA collection is beneficial because arrestees are more likely to have committed other crimes but hypothesizes that this logic can also be applied for other subgroups as well. For instance, young men, residents of particular neighborhoods, individuals from particular socioeconomic or educational backgrounds, or any other group that has a high incidence of criminal activity can be accused.

The main issue people have with DNA tests is privacy. An individual's DNA is immensely more exclusive than a social security number and in the wrong hands, your life could be at risk. If a database filled with millions of DNA samples from people all around the world; it takes only one person to breach the “security” and peoples DNA would then be readily available to anyone in the public. People can potentially analyze your DNA and see what bacteria or viruses your DNA is most vulnerable to, and use it against you. Additionally insurance companies could potentially obtain the results of a DNA test and see that you have an incredibly high probability of developing breast cancer.

Today, the FBI has DNA records of more than 5 million convicted offenders in the database CODIS, or Combined DNA Index System. However, DNA fingerprinting has limitations: it is limited to directly connecting crimes to felons already in CODIS, has high risk of contamination, does not look at familial records, and only analyzes short pieces of DNA. With the advent of more affordable and high resolution genetic technologies after The Human Genome Project, over 35 million people have submitted their DNA to the largest direct-to-consumer genetic companies. Two companies, FamilyTreeDNA and GEDmatch, also allow law enforcement access to their databases. Thus, beginning investigative genetic genealogy, a new method of forensic investigation not only with higher resolution DNA information than DNA fingerprinting but also the capability of finding a suspect from distant relatives.

160 Words | 1 Pages

In the book picking cotton a young woman’s life was haunted by a terrible crime while a young man’s life was ruined by false accusations and evidence. This book is one which many can relate to, due to the fact that that we live in a society where crime as such happens everyday and situations such as lack of evidence and false accusations put people in jail for crimes they did not commit. In our genetics class we learn a lot about how DNA plays an important role in our lives. The book makes me take this way more seriously than I did when talking about it in class because it shows how a simple sample of DNA can rid someone of a lifetime in prison for a crime they did not commit. Ronald Cotton was accused of a crime he did not commit, after 10

Persuasive Essay On Misdemeanor Convicts

661 Words | 3 Pages

While there are many arguments out there as to why an individual who has been convicted of a misdemeanor crime should have his or her DNA collected, we must not only look at the practicality of this, but also the facts. A law of this magnitude could open the flood gates to a massive invasion of privacy. Many supporters of this law claim oftentimes misdemeanor convicts go on to commit more serious crimes, so having their DNA in the system will help identify them sooner if they commit a crime. This invasion of privacy not only assumes that a misdemeanor convict will become a serious convict in the future,

In my opinion through the evidence shown throughout the years DNA sampling should be collected on the first offence. Privacy and the right to your own body are important, but the right to feel safe from your attacker is also important. Collecting DNA samples would reduce the crime rate, free those who have been wrongly convicted, and finally give justice to those attacked by putting those criminals behind

Eyewitness Testimonies

142 Words | 1 Pages

I completely agree with all the points you made. DNA is the most reliable source of evidence for the fact that it directly and often times unquestionably ties an individual to a crime. On the other hand, eyewitness testimonies rely on memory and as we now know that can be a problem as memory is reconstructive and that means our memories may be altered by suggestive techniques, pressure, rumor, or hearsay. Eyewitness testimonies are also particularly vulnerable to errors when the suspect’s ethnicity is different than the witness’s, leading questions are given to the witness, and when witnesses are exposed to misleading information. However, until DNA came around people were willing to dismiss results of memory research as that was the only source

Fourthly, Forensic Anthropology is important to crime scene investigation where it makes it possible to determine age, height and gender of human remains found at a crime scene ("Importance of Forensic Science in Criminal Investigations and Justice," 2018). On a crime scene, human remains can be found whether decomposed, burned, buried, mutilated, destroyed from an accident or otherwise unrecognisable ("Importance of Forensic Science in Criminal Investigations and Justice," 2018). Forensic Anthropology is a study that identifies these persons from their skeleton, bones or unrecognisable state that was left on the crime scene ("Importance of Forensic Science in Criminal Investigations and Justice," 2018). The remains of bones that are left on the crime scene are collected by the CSI and sent to a forensic lab. It is analysed in a forensic lab where the sex can be determined by using the pelvis.

DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
