Moreover, the technique involved is less invasive than taking a blood sample and is extremely reliable when done properly. So, even those evidences that are gathered from very old crime scenes can still be used by authorities. Also known as DNA profiling and genetic fingerprinting, this method has been used by courts, forensics and health insurance companies.
There is a lack of privacy. Final Thoughts The profiling of DNA has begun in the s after scientists discovered the VNTR or variable number tandem repeats in the hair strands of blood-related individuals. It can also be utilized to identify a decomposed body and to determine who the suspect is in a crime.
There have been cases wherein DNA evidence was planted at crime scenes to accuse the wrong person. A smudge of saliva on a drinking straw is more than enough for DNA sampling.
It can be used to determine paternity. If people of a particular ethnicity are arrested more often than Pros and cons dna profiling ethnic groups, the databases will reflect a higher genetic pool for that group.
One of the most important disorders to discover is called PKU, or phenylketonuria. The ease with which DNA can be obtained without consent from various biological samples left on objects used in daily life aids in the violation of a person's privacy.
If you are eager to know more about this scientific method, it would be helpful if you got knowledge about its pros and cons. Despite its being highly accurate, this is not free from flaws. Several countries nowadays maintain DNA banks of people who committed crimes.
Here are some advantages and disadvantages of this scientific identification method. Careful consideration should be done before profiling any individuals DNA or agreeing to undergo one.
If the need for identity is immediate, genetic fingerprinting might not be the ideal method. After amplifying the STRs, scientists then start counting the repeats. It is also more accurate as long as it is forensically valuable while blood samples can be tampered with.
With current technology, a collected sample of DNA that has been analyzed can be saved in a database indefinitely. While some agree on its use, there are also people who are vocal about their disagreement.
There are concerns about tampering which can also lead to wrongful convictions. But just how accurate and reliable DNA fingerprinting is in identifying criminals?
In a crime scene, forensics can collect and store samples for future reference, or directly match the samples with current data. Databases of DNA information could be potentially accessible because of security vulnerabilities, creating third-party access to DNA fingerprinting information that could lead to a whole new form of identity theft.
Sometimes referred to as genetic fingerprinting, the primary advantage of this forensic process is that it adds another layer of evidence in criminal proceedings. This can work in the favor of a child if there is an issue of child support or is an offspring of a foreign father and this is needed for immigration purposes.
DNA fingerprinting is a complicated and time-consuming procedure that needs sophisticated machines and fully trained lab specialists. Imagine receiving individualized advertising based on your DNA.
Just a small amount of human error such as exposing the sample to other substances or incorrectly identifying two samples as identical can ruin the process or alter the results. This can also be used to prove or disprove certain consanguinity claims.
Another advantage of applying this scientific process is in paternity cases where the identity of the father of a child can be discovered by comparing the DNA of the child to that of the DNA of the possible father. DNA fingerprinting is also very helpful in identifying cadavers during massive deaths, and in disproving or proving kinship of certain individuals.
Human error also plays ab big part in confusion and labeling.
It helps people know more about their family background. The DNA from a tooth and thigh bone, fossilized in Spain, were sequenced by scientists in from samples that were believed to be overyears old. However, this technique has serious risks for the child as well as mother and hence it is advisable to go for postnatal DNA testing.
What we need to ask ourselves is this: This can work in the favor of a child if there is an issue of child support or is an offspring of a foreign father and this is needed for immigration purposes.However, DNA profiling is not all good as there are cons or disadvantages of this process.
But before we take up the various pros and cons of DNA fingerprinting, we need to understand what it is and the various processes it requires. List of Cons of DNA Fingerprinting. 1. It is a violation of human rights.
One of the reasons that there are opponents of DNA profiling is the argument that it is some sort of harassment and a violation committed on private individuals who are subjected to one. List of Cons of DNA Fingerprinting. 1. It is a violation of human rights.

But before we take up the various pros and cons of DNA fingerprinting, we need to understand what it is and the various processes it requires. DNA profiling is one of the most reliable methods used for establishing personal identity. Here, we will provide some information about DNA profiling process and forensic DNA profiling.
Pros and Cons of Profiling of the DNA. Pros. DNA profiling helps elimination of innocent suspects and sets them free. It is a means of rapid identification.
When it comes DNA profiling, there are certainly some pros and cons that must be weighed when considering the value of this practice. Here is a look at both sides of the equation. The Pros of DNA Profiling.Download
