DNA Technology and its Application to Disease

            DNA technology has noted significant progression since 1990 and has become an essential diagnostic measure within medical laboratories. First, it is utilized during the detection of diseases through replication of DNA strands associated with a given ailment. The clones are then employed in tracing the presence of ailments or faulty DNA structuring that also contributes to various ailments. This has been highly employed in the analysis of AIDS especially within developing and underdeveloped nations and thereby underlining the technology’s significance. Secondly, recombinant DNA is utilized in gene therapy where DNA replicas are created to replace defective ones (Solomon, Linda and Diana 282). DNA extracted from bone marrow acts as the best form of recombinant DNA due to high replication levels. This approach has been helpful in overcoming genetic disorders like klinefelters syndrome that is being noted in at least one in every five hundred males. With the given ailment occurrence, DNA technology is highly demanded.

The third application in DNA technology is noted in forensic work, as it is very useful in crime scenes for analysis purposes. Criminal patterns have progressed with many incidents noted as being impeccably performed and thus DNA technology becomes helpful. Fourth, DNA modification is highly useful in cultivation practices especially in the creation of resistant crops. With global warming and the enhancement of desertification in various regions, the technology has aided with the creation of crops that endure adverse weather patterns (Solomon, Linda and Diana 285). DNA technology has demonstrated its usefulness and effectuality as identified within the presented areas and therefore as more investigations are accorded for technological progression, the technique will be highly used in the future. Additionally, cost elements within the subsequent years, say three to five years, will be lower thereby creating an opportunity for enhanced usage.

DNA technology has been intensively employed within the criminology field. Law enforcers have incorporated DNA knowledge with computerized systems in the creation of the Combined DNA index system, mainly referred to as CODIS that allows storage of DNA materials from individuals such that when a search is created, identification is achieved through the likening mode (Federal Bureau of Investigation, 2011). With increased crime instances, DNA testing through the CODIS has created a restraint with the system being overwhelmed by the workload. Therefore, the government cites a prospective need for the program’s expansion in a bid to effectually deal with the program’s demand. Presently, due to the change in weather patterns, the agricultural technology remains the most appropriate DNA technology from a subjective standpoint. As rainfall becomes more inadequate in various regions due to global warming, DNA technology is useful as it supports the creation of enhanced crops in terms of temperature resistance and minimal water utilization.

Presently, African nations notably Kenya, Ethiopia and Somali have noted famine patterns necessitating food supplements from other regions (Mitchell, 2011). The Sub-Saharan regions and other arid sections of the world bear increased likelihood of such food deficiency. In fact, investigators have ascertained that the Sahara progresses towards the south by about ten kilometers per year. Within the US, the southwest region evidences the same tendency and climatologists have noted that within the future periods aridity will be amplified. Therefore, in anticipation of such situations DNA technology should be employed in creating favorable crops as a means of food safeguard (Solomon, Linda and Diana 285). Following this interest, I would like to study agricultural modifications on crops and employ the knowledge in assessing whether such plants hold long-term health impacts on the human populace. This is because the scientific community has been able to ascertain that DNA modified crops pose no health challenges to individuals within the short-term yet the same cannot be said authoritatively in regard to long-term effects.
