 The Benefits of Crispr Technology and Its Resistance to Outside Contaminants

CRISPR technology is fast becoming a hot topic among medical researchers. CRISPR is simply a family of genetic sequences located in the chromosomes of living organisms like bacteria and Archaea. These genetic sequences are typically derived from strands of DNA known as DNA. They are employed to identify and destroy micro-organisms during subsequent infection. This means that the organism has been "infected" by another micro-organism and is then treated accordingly.

There are many uses for this exciting new technology, however, one of the most popular is for the study of human health and disease. As we know too well, the human body is home to many foreign organisms that we would not wish to get on with. The human immune system is particularly vulnerable to these "perceived" diseases. This is why research is turning towards developing methods of countering this bacterial immunity. As we are finding out more about the role of bacteria in disease, we are also coming up with more ways to defeat it.

One of the first applications of crispr technology was for editing microbes. In November of 2021, scientists announced that they had successfully edited the coding of the mammalian transcript, making it two steps shorter and more appropriate for translation into proteins. This means that researchers can now make more genetically customized medicines that target specific diseases. Earlier this same year, another group of researchers announced that they had successfully edited the genetic coding of the virus that causes AIDS. The virus has been dubbed as a retrovirus because it invades the genetic material of healthy cells.

The hope with these genetic diseases is that the engineered viruses will help fight off the host immune system once it becomes compromised. If successful, this could mean the end to major outbreaks of seasonal flu, bird flu, swine flu, and other illnesses. For animal lovers and farmers, this means less spending on vaccines and fewer sick animals. For human beings, it means better health and a longer lifespan. All the benefits with none of the drawbacks.

The CRISPR technology used by scientists to accomplish this feat is relatively simple. It involves snipping a small piece of DNA with a laser, cutting it to fit the precise location of a mutation that results in the formation of a harmful protein. This piece of DNA is then introduced into an organism's genome. If the DNA matches the targeted trait in the targeted organism, it initiates the transformation. Human and mouse cells are easily transformed using this technique, allowing scientists to study gene editing in greater detail than had been possible with earlier methods.

Scientists have raised some ethical concerns about human embryonic stem cell research using this off-target effect. They worry that the insertion of the wrong gene may cause a change in a person's appearance or disease symptoms. However, many ethicists and bioethicists argue that it is impossible to tell whether the insertion of an incorrect gene will harm a person, because everything occurs in the future. No one knows what the long-term effects of Crispr will be.

Another worry is that the technology will make it easier for harmful germs to evade detection. The concern here is not so much about current or future cases of resistance, but about potential viruses or bacteria escaping from the genetically altered seeds and getting into the wild. Many microbes do escape from genetically altered crops and, in fact, experts have already tested their survival in wild settings. In theory, if scientists can get a wild type of disease to survive for a few months in the laboratory, why wouldn't they be able to get it to resist the same procedure in the field? It is possible that resistance could be built up in the field after that first field trial.

The concerns regarding the potential dangers and the difficulties in enforcing genetic modifications in crops are valid. However, with appropriate safeguards in place, the benefits of Crispr technology will far outweigh any potential downside. One way that researchers and technicians have attempted to guard against escape viruses is to control breeding by ensuring only a single seed is used in a laboratory experiment. That way, if an escape seed does get into the field, it would be more difficult to cultivate. Another way that Crispr technology may be enforced more strictly is by making it harder to use genetic targets.
