The many benefits of using DNA technology are well known and include such things as its ability to identify specific disease markers, create family trees, or even establish an individual’s biological relationship with another person. However, there is one major disadvantage to using this technology that can cause serious problems if it isn’t taken into account: privacy rights.
1-The Disadvantages Of DNA Technology
One disadvantage of using DNA technology is how expensive it can be to get your genetic profile tested, as the only company that offers these services does not provide low-cost options. Some other disadvantages to testing for your genes are that it may take longer to get results and if the battery goes out on a particular gene chip, all your data may be lost.
Another thing is you might find out information about yourself that you didn’t know before, like inheriting certain health problems, which could impact you emotionally. Lastly, although there are some positives to having access to your genes (like screening for diseases) there are also some negatives (such as finding out unexpected information) and so people should consider both sides before deciding whether or not they want their genes screened.
2-The High Cost Of DNA Technology
It’s difficult to say that there are disadvantages to using DNA technology, but the high cost to use it for personal use is one thing that may be considered as such. Not only does it take quite some time and effort to collect enough materials for testing, but the tests themselves can be expensive.
For example, in order to test for diseases like cystic fibrosis or Huntington’s disease, you will need to collect tissue samples from yourself and then ship them off to a lab where they will be tested at an average price of $600 each. If you have more than one member in your family that needs these tests done, the costs can quickly add up.
3-The Possibility Of Human Error
One disadvantage of using DNA technology is the possibility of human error. For example, if you’re looking for a set of siblings and you’ve identified two potential matches, it’s possible that the lab analyst got one sibling’s data mixed up with the other sibling’s data.
This can happen either by typing in the wrong number or by misreading the number on an electronic spreadsheet. For instance, say you typed into your spreadsheet that sister A was born on September 1st, but when you went back to update her birth year to 2017 (to reflect her actual age), it automatically changed her birth date to September 10th because there are only two digits available for both fields.
4-The Potential For Abuse
DNA testing has been used for many purposes, but it can be easily abused. If an individual’s DNA was found at the scene of a crime, there is currently no way to tell if they were in fact the perpetrator or had just been in contact with the perpetrator.
The lack of regulation surrounding this type of testing leaves opens the possibility for abuse because it can’t always be verified that an individual was present at the crime scene.
5-Cons Of Recombinant DNA Technology
Recombinant DNA Technology has many advantages, but it also has some disadvantages. One of the disadvantages is that recombinants are often transformed in vitro, meaning outside the cell. This can lead to changes in protein expression, as well as a loss of natural post-translational modifications.
Another disadvantage to Recombinant DNA Technology is that it can lead to new variants which may be more difficult for the immune system to recognize.
6-The Golden State Killer Case
In April 2018, police announced that they had arrested the man behind the Golden State Killer case. The suspect, who was identified as 72-year-old Joseph James DeAngelo Jr., was found after investigators used a genealogical website to find his family tree.
They then narrowed down their search to the town where he lived and finally found their man when they checked his property records and saw that he owned a car matching the description of one seen by an eyewitness in one of the attacks.DNA profiling has become increasingly popular in recent years as new cases have been solved through this method, but it’s not without its drawbacks.
7-Ensuring People’s Rights Over Their DNA
When people get their DNA sequenced, they sign away any rights over the data. This means that it can be used by law enforcement or research companies without their consent.
There are laws to protect against this in Europe, but this is not the case in America. This can lead to people being unfairly profiled or incriminated for crimes they didn’t commit.
8-Applications Of Recombinant DNA Technology
- Recombinant DNA technology is used to sequence and study genomes of organisms, such as in the Human Genome Project.
- Recombinant DNA technology is also used to study genetic diseases, such as Huntington’s disease.
- Recombinant DNA technology can be used to create genetically modified animals.
- The recombination of genetic material between two different but closely related species is called chimerism. Chimerism can occur naturally through fertilization or during times of organ transplantation when the transplanted organ has cells from the recipient in it.
9-Limitations Of Recombinant DNA Technology
Recombinant DNA technology has many advantages, but also some limitations. For example, it is impossible to create a human with recombinant DNA technology because there are some sequences that will not be able to get through the embryo stage due to restriction enzymes.
Another limitation is the size of the genome; although there are new techniques that allow for smaller genomes to be created, they are still substantially larger than natural genomes.
