Human Life And Technology: The Benefits Of Genetic Engineering

1974 Words 8 Pages
Genetic engineering is a very powerful and potentially dangerous scientific application used to modify/alter an organism 's DNA. This technique uses biotechnology, which is the use of genetic engineering for commercial purposes, to introduce a desirable trait into an organism by affecting it on a molecular level (UNL 's AgBiosafety for Educator). These kinds of methods involve the addition, replacement, or deletion of certain strands of DNA. Introductions of DNA can come from either the same or different types of organisms. The topic of genetic engineering has been a controversial issue ever since it was first brought to light in the 1970s. There are some who say this advancement contains beneficial opportunities for society, while others …show more content…
According to the Biotechnology Industry organization (BIO), approximately 10 people die each day waiting for organs to become available (The Benefits of Genetic Engineering) .With methods like tissue engineering, new organs can be grown to replace those that malfunction or shut down. With cell transplants, cells can be used to imitate the function of the organ that people are waiting for and keep them alive long enough for them to receive the actual organ. In the last century, there has been a sufficient increase in life expectancy of the average person, genetic engineering could make the time spent here much longer. As humans get older, there are certain illnesses such as Alzheimer’s and Cystic Fibrosis that can develop and end up ending one’s life earlier than expected. Genetic modification would allow scientists to reverse some of the reasons for which the body starts to naturally decline on a subatomic level, thus improving lifespan (Pros & Cons of Genetic Engineering). With longer lifespans, humans would also gain the potential to adapt to their surroundings much faster than …show more content…
The reconstruction of gametes in genetic engineering would result in a permanent change in the organism, as well as for future generations (Zimmer). Should there be a negative effect from these changes, this problem could then be passed on. In addition, tampering with one’s genetic makeup could lead to a loss of genetic diversity/ natural variation. With little variation in personalities or looks in a modern society, the formation of new genes from the gene pool would come to a halt, thus making adaptation to certain environments difficult for certain organisms(Zimmer). Genes that would become useful in certain circumstances, would be bred out. Another problem that is presented with all types of genetic engineering is the interdependence of genes. This is the effect that genes have on one another, one gene may code for several features, while several genes are required to code for one characteristic (Zimmer). When a gene is removed, it cannot be entirely known what other aspects that gene codes for, the same principle applies when inserting a new gene, it may have other unknown functions. The resulting effects from the unknown gene functions could be seen right away, while others could contain long-term effects that are harder to
