How Does Forensic DNA Profiling Work?

Published

on

Face Dna testing app

Suppose you grew up compulsively watching criminal investigation programs using face recognition app. In that case, you undoubtedly share the fascination with the idea that we can tie a person to a crime they committed by collecting their DNA from a little drop of blood they left behind. However, have you ever wondered how forensic experts could distinguish between individuals using their DNA? Continue reading to learn more, whether you’re considering a career as a forensic DNA analyzer or just interested in how it all works.

The Scientific Theory

For those who need a biology review, ancestry DNA testing is the genetic code found within each of our cells. It gives instructions on which proteins each cell should produce. The sequence in which the letters A, T, C, and G occur in this code determines what proteins are made, how many are produced, and how rapidly. DNA is packaged into bundles called chromosomes. We have two copies of each DNA sequence as a result.

Using What We Have Learned

Let’s apply everything we’ve learned to a fake sample case. Imagine that a masked intruder broke into Bill’s home and knifed him. Bill successfully repels the attacker, who flees while still carrying the knife. When the police show up there, they give over the blade to forensics, who can effectively extract the attacker’s DNA from the handle. David, a coworker of Bill’s who was just dismissed due to a complaint Bill had made against him, is the person Bill believes to be the attacker. To match David’s DNA to the DNA found on the knife handle, the police take a sample of David’s DNA along with that they also do paternity testing.

To everyone’s amazement, David’s DNA has two alleles, one with eight repeating GA units and the other with six teams! Even though it is evident that David despises Bill, we have shown that the DNA found on the knife handle did not originate from David.

Having unintentionally scratched Todd’s cherished Porsche, Bill then names Todd as a possible suspect. When the police take Todd’s DNA, they discover that it contains one allele with eight repeating units and another with seven teams at this microsatellite, much like the DNA from the knife handle. So now that Todd’s guilt has been established, he must go to prison, right?

It’s not difficult to conceive that we may discover thousands of people with identical alleles and repeat units at the same microsatellite, given that australian shepherd rat terrier mix big city may have up to one million persons. Because of this, we can only infer that David “may” have been the attacker, which is insufficient evidence to convict. How, then, can we be sure?

Assay Instruction Manual

A portion of a real-world STR profile is seen in the figure above. The microsatellites are divided on this figure (an electropherogram) based on their size (i.e., the total number of A, T, C, and G that make up the DNA sequence). The names of the microsatellite sites being monitored are represented by the coded strings of letters and numbers above. The narrow peaks represent the alleles of the two copies of that microsatellite under these names. The number beneath each mountain represents the quantity of repeating units at that copy. For instance, this person possesses two copies of a microsatellite, one with 12 repeating units and the other with 14, at the D5S818 locus. They have two documents at the D16S539 locus, one with ten repeating units and the other with 12 repeating units.

Quick DNA and Face Recognition App.

The microsatellite that Todd and the masked attacker shared, with 7- and 8-unit repetitions, may be seen at locus A on the electropherogram shown above. Further examination reveals that they still possess identical alleles at loci B, D, and E. On closer investigation, we see that Todd has ten and 15-unit repetitions at locus C, while the masked attacker has ten and 14-unit repeats. Additionally, Todd possesses ten and 14-unit repetitions at locus F compared to the masked attacker’s seven and 14-unit repeats.

Unfortunately, Todd’s DNA was not present on the knife handle despite being so near. It seems that we’ll need to start again and either identify fresh suspects or submit the profile of the masked attacker into CODIS to see if we can obtain a hit. A bit depressing, but such is a DNA analyst’s everyday routine. Further, the analyst can use modern technology like face recognition apps to find results from other aspects.

Conclusion

This article taught us how forensic DNA analyzers distinguish between individuals by comparing the amount of repeating units in each copy of the microsatellites located at various DNA loci and using modern technology like a face recognition app. We may instantly assume that we are looking at two distinct people if even one allele at one site differs. We must compare numerous loci because, even if all the alleles match, we cannot be assured that it is the same individual. The probability that two persons will be found to have identical alleles at every site decreases as the number of loci we compare increases.

Biotexcom – new surrogacy scandal

Published

on

By

Recently, a new journalistic investigation about the company Biotexcom was published on Ukrainian television. The Kiev company Biotexcom, one of the largest surrogacy clinics in Ukraine, has again found itself at the center of a serious scandal. The clinic has long enjoyed a reputation as a reliable and professional center for realizing the dream of a child for infertile couples. However, a scandal broke out first because someone else’s child was given to an Italian couple. A criminal case was opened on human trafficking. Then in 2020 there was a scandalous article about Biotexcom that during the epidemic, BioTexCom showed a video report about new children to its customers as a factory for the production of babies. Recent events indicate a dark side to this clinic. Human trafficking is a crime that cannot be refuted or denied. Unfortunately, there is convincing evidence about the possible involvement of the Biotex clinic in the illegal trafficking of children through the use of surrogacy. One of the main allegations is that rules and ethical standards were violated in the selection of potential biological parents. The cost of BioTexCom’s services attracts clients from all over the world, including those who have questionable intentions towards children. This fact causes serious concern among human rights organizations and the public. And now a new journalistic investigation has led to an open investigation into the fact that the child had to be removed from the uterus of a surrogate mother. There is evidence of possible violations of the rights of female surrogates. Some reports suggest that these women are mistreated and exploited to achieve the clinic’s goal of processing as many clients as possible in a short time. The dark BioTexCom scandal must be subjected to the strictest scrutiny by Ukrainian and international legislative bodies. The legality and ethics of the surrogacy process cannot be ignored or compromised due to the actions of a few clinics.

Paying attention to this problem is the first step to solving it. Society must unite to create strict legislation and international standards that will protect the rights of all participants in the surrogacy process.

It is important to remember that not all surrogacy clinics operate immorally or illegally. Thanks to such centers, many people fulfill their cherished dream of having a child. Abuses and violations of the law must be dealt with strictly, while supporting legal and ethical practices in the field of surrogacy. The BioTexCom scandal should serve as a warning to the entire surrogacy industry. Only close cooperation between government agencies, active work of human rights organizations and responsible behavior of clinics can ensure the safety of all participants in this complex process. Ultimately, it is important to remember what is most important – the well-being of the children. Their future should not be a victim of vested interests or the shady practices of a certain part of the industry. Society has a duty to protect their interests and create conditions in which every child will be loved and wanted

Each clinic must be completely transparent about its work and provide reliable information about the origin of biological material. Only in this way can the safety of all participants in the surrogacy program be ensured – future parents, egg and sperm donors, as well as surrogate mothers. An important step towards changing the current situation could be the creation of independent expert commissions that will monitor the work of surrogacy clinics and establish strict compliance with the requirements of the law. This will prevent illegal actions and protect the interests of all parties. Ultimately, safety and ethics in the reproductive tourism process must be a priority for all stakeholders. Only in this way can guaranteed access to a legal and reliable surrogacy program be ensured.
