How is it different from traditional agricultural breeding What is and ? Synthetic uses new techniques combining biology and COMPLEXITY OF HUMAN INTERVENTION engineering to make new or modified living things and materials. Throughout history, humans have strived to create COMPLEXITY more desirable products such as food that is easier to grow and tastes better. Synthetic biology builds on the science of Synthetic Natural agricultural breeding and genetic engineering to create new things faster and cheaper in even more controlled and specific Traditional agricultural ways. The field is exploring where biology-based products breeding might provide solutions to a wide diversity of problems in Genetic engineering Biology? health, energy, and the environment.

Humans have been using selective breeding for 10,000 years to improve Genetic engineering is a way to speed up and control the Synthetic biology is a new way of combining biology and engineering to create agricultural plants and . Farmers choose seeds for future planting process by altering or inserting specific genes into a new living organism. new or modified living organisms and materials that do not currently exist in from plants with the best traits selecting for taste, color, disease resistance, the natural world. Scientists can insert individual genes from one living organism into another and productivity. using methods. DNA does not need to come from a closely Scientists are developing a library of standard biological parts with known Farmers and scientists have been cross-breeding closely related species related species. functions that can be put together in combinations that may not exist in nature. for hundreds of years to create new hybrids. Scientists have used genetic engineering to create plants with desirable Using building blocks of DNA, scientists create modified or new living organisms. Crossbreeding can occur only between closely related living organisms. traits such as increased productivity, disease resistance, increased Synthetic (human-made) DNA can even be printed using a special printer. Hybrids inherit a mix of genes from both parent plants including both nutritional value, and herbicide resistance. With synthetic biology, cells can be programmed to become tiny factories that positive and negative traits, it is not specific to just one . produce new materials. New materials can be grown from modified bacteria, algae, or yeast.

EXAMPLES: EXAMPLES: EXAMPLES: Most modern fruits and vegetables are hybrids of ancient wild plants. Almost all corn, soybeans, cotton, sugar beets, and canola plants grown Future synthetic biology products may include new materials, Cross-breeding has created many new and unique varieties. in the United States are genetically modified organisms (GMOs). energy sources, medicines, and food.

GENES & DNA CELL Genes are a set of instructions that determine how a living organism forms and grows. Genes influence what we look like on the outside and how we work on the DNA inside. Genes are made of a chemical called DNA (deoxyribonucleic acid). DNA molecules are located inside a cell nucleus; DNA carries information and can copy itself. Adenine (A), thymine (T), cytosine (C), and guanine (G) are the four GENE nucleotides found in DNA. CHROMOSOME
