Genetically Modified Foods
80% of all crops and produce that are consumed in the United States are genetically modified. Genetically Modified Foods are plants or animals that have undergone a process wherein scientists alter their genes with DNA from different species of living organisms, bacteria, or viruses to get desired traits such as resistance to disease or tolerance of pesticides. It is my intention to show the negative side effects of GMO products; which explains why so many people are becoming increasingly concerned about consuming GMO products.
First let’s start with what GMO’s are and how they are created. The way GMOs are created disrupts the plant’s DNA in unintended, potentially harmful ways. In genetic engineering, a single gene is removed from one organism and forcibly inserted into another. First, scientists identify the gene they want and analyze its sequence. If the source gene is to be taken from bacteria, some of its sequence has to be rearranged because bacteria produce certain amino acids using a code different from the one used by plants. After figuring out a working gene sequence, engineers add a promoter sequence at one end of the gene to turn it on (the most popular one in GM crops being CaMV 35S, which forces the gene to constantly churn out the protein), and a terminator sequence at the other end (which tells the DNA to stop). Lastly, scientists add a marker gene, usually one that promotes antibiotic
