In The Past 25 Years We Have Learneda Lotabout Dna And Arenow Abl

In the past 25 years, we have learned a lot about DNA, and are now able to manipulate genes. Plants are genetically modified to possess desirable traits such as resistance to disease and to grow with less water and fertilizer. There are even certain Idaho potatoes that all grow to the same size, so McDonald's french fries are the same length! Human genes are inserted into bacteria to inexpensively produce drugs that treat diseases. Soon, non-life threatening cosmetic changes will be available for those who can afford them.

One of the most fascinating recent developments in genetic engineering is the creation of genetically modified mosquitoes aimed at controlling the spread of vector-borne diseases like malaria and dengue fever. Scientists have successfully inserted genes into mosquito genomes to either reduce their lifespan or render them incapable of transmitting the pathogens responsible for these diseases. For example, Oxitec, a biotech company, developed genetically modified Aedes aegypti mosquitoes that are male and sterile. When these sterile males are released into the wild, they mate with female mosquitoes, resulting in the death of their offspring, thereby reducing the mosquito population over time. This method has shown promise as a sustainable alternative to chemical insecticides, which often have negative environmental impacts. Field trials conducted in regions such as Brazil and the Caribbean have demonstrated significant reductions in disease-carrying mosquito populations without harming other insects or the surrounding ecosystem. This innovative approach leverages natural biological processes and offers a promising tool in the global fight against mosquito-borne diseases. As research progresses, it is hoped that such genetically engineered mosquitoes will become an integral part of integrated vector management programs, providing a safer and more effective means of disease control than traditional methods (Alphey et al., 2012; Benedict et al., 2013; Delatte et al., 2017; Hegde et al., 2017; James, 2005; Kirst et al., 2018; Nabi, 2018; Ritchie et al., 2020; Schlamp et al., 2019; WHO, 2018).
