The question of why DNA technology is important for disease prevention is not as simple as one might think. In fact, there is no simple answer to this question. However, in spite of the complex answer, we can still point to genetic differences between various strains of bacteria and fungi as the reason why some strains cause disease while the others do not. Basically, this means that prevention is more important than cure. But how is this so?
It is important to understand: why genetic differences exist between strains of bacteria and fungi. Strain means that a certain type of bacterium has been altered somewhat in its nature. Now, it is important to point out that a slight difference in one trait does not mean that the strain will cause disease. On the contrary, if two strains are similar, then it is more likely that the changes have caused the strain to grow faster than its counterparts and this in turn might have implications for the spread of the disease.
It is also important to point out: that even minor genetic differences between closely related strains can lead to disease. For instance, most types of bacteria that cause colds and allergies are closely related. In this regard, a strain that is known to cause colds is the cold strain while another known to cause allergies is the allergy-triggered strain. So, if the medical world were to use such technology as the basis of preventing diseases, then all kinds of ailments that are associated with the immune system would be susceptible to this technology. Indeed, this line of reasoning makes a lot of sense.
To put it simply, the reason why DNA technology: is important for disease prevention is that this kind of technology allows researchers to manipulate the genome – the entire set of genetic instructions that ensure each and every cell in the body to perform specific functions. Once the cells are manipulated by scientists in this manner, it is then possible to introduce new information or insert new genetic information into the system. Thus, it is now possible to reprogram the body and this in turn may allow the body to fight diseases or perhaps to even avoid getting sick in the first place.
There is still a lot of research that goes on in this field: For instance, more is learned about the role that the genetic code plays in diseases like Alzheimer’s and diabetes. This technology will no doubt continue to improve and grow and this is a key factor why it is important for everyone to get involved in it today. The reason is simple: without good genetic information, it is nearly impossible to prevent most major illnesses. Unfortunately, most parents don’t realize this important fact.
The other aspect about why DNA technology: is so important for disease prevention is that there are countless uses for the same. For instance, it is now possible to clone yourself and thus preserve your genetic information. If you are facing a health crisis, such as a debilitating disease, it is also possible to use the same to get the help you need. In fact, today, there are clinics all over the country that utilize this technology in order to help their patients. In short, the advances in this field have created a world where diseases such as Alzheimer’s and diabetes are dealt with and preventable and we are only just beginning to scratch the surface of what can be done with genetic information.
