Genetically Modified Organisms (GMO)
Transcript of Genetically Modified Organisms (GMO)
(GMO) How to Genetically
Modify A Seed Using the basic techniques of genetic engineering, a gene from one organism can be inserted into cells from another organism; creating organisms that are transgenic (meaning they contain genes from other organisms). This experimental technology merges DNA from different species, creating combinations of plant, animal, bacterial and viral genes that cannot occur in nature or in traditional crossbreeding. Virtually all commercial GMOs (agriculture based) are engineered to withstand direct application of herbicide and/or to produce an insecticide. In the U.S., GMOs are in as much as 80% of conventional processed food. Step 1: Find a new trait
Step 2: Get appropriate genes
Step 3: Trait insertion
Step 4: Observe
Step 5: Plant
Step 6: Gene expression Next Time... Gene splicing is cutting a gene from one organism and pasting it into the DNA of another so that a characteristic can be transferred from one plant or animal to another. For example, bacteria transformed with genes from human proteins can now produce pure human insulin. GMOs, or “genetically modified organisms,” are plants or animals created through the gene splicing techniques of biotechnology (also called genetic engineering, or GE). This transgenic tobacco plant, which glows in the dark, was grown from a tobacco cell transformed with the firefly luciferase gene. The plant illustrates how DNA from one organism contains information that can specify traits in another organism.
