Document Summary
Humans have been manipulating living things for thousands of years. Produces variety in living things reduce hunger and promote growth. Refers to a series of research development and technology transfer initiatives. Aimed to increase agriculture production around the world beginning in the late 1960s. Explain ways that plants can be genetically modified. Explain the different types of traits that have been introduced into plants improved yields improved pest resistance improved herbicide tolerance. List at least 3 genetically engineered plant species that have been approved for commercialization. Discuss concerns over genetic modification of plants and animals. Selective breeding: manipulating living things with desired characteristics. Allows only those with wanted characteristics to produce the next generation. Agrobacterium tumefaciens: natural transformation system for plants. Transgene: genetic material transferred from one organism to another. Mutagenesis: genetic information of an organism is changed, resulting in a mutation. Dugs produce cells that have many times the normal number of chromosomes.
