Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells. Systems of specialized cells within organisms help them perform the essential functions of life.Īlignment agreement: Thanks for your feedback! All cells contain genetic information in the form of DNA molecules. This lesson focuses on the following Three Dimensional Learning aspects of NGSS:Ĭonstruct an explanation based on valid and reliable evidence obtained from a variety of sources (including students' own investigations, models, theories, simulations, peer review) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.Īlignment agreement: Thanks for your feedback! Analyze the benefits and drawbacks of manipulating an organism's DNA.Ĭonstruct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.Ĭlick to view other curriculum aligned to this Performance Expectation.Describe general techniques used by genetic engineers to modify DNA.List several present day applications of genetic engineering.

Once each gene is classified, engineers develop ways to alter them to create organisms that provide benefits such as cows that produce larger volumes of meat, fuel- and plastics-generating bacteria, and pest-resistant crops.Īfter this lesson, students should be able to: Applications for genetic engineering are increasing as engineers and scientists work together to identify the locations and functions of specific genes in the DNA sequence of various organisms. Genetic engineers have developed genetic recombination techniques to manipulate gene sequences in plants, animals and other organisms to express specific traits. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).

Students fill out a flow chart to list the methods to modify genes to create GMOs and example applications of bacteria, plant and animal GMOs. They learn what genetic engineering means and examples of its applications, as well as moral and ethical problems related to its implementation. Students learn how engineers apply their understanding of DNA to manipulate specific genes to produce desired traits, and how engineers have used this practice to address current problems facing humanity.
