Authoritative PPT Summary
"Modern Biotechnology" PPT courseware
Part One: Scenario Introduction
In 1953, Watson and Crick proposed the double helix structure of the DNA molecule, uncovering the gene and triggering a revolution in the field of life sciences. In 1997, Willamette set off a "cloning trend" that shocked the world. The research results of the "Human Genome Project" in 2000 slowly opened the curtain of the 21st century life science century. Cloning technology, transgenic technology, etc. are all modern biotechnology .
learning target
1. Outline the concept of modern biotechnology.
2. Give examples of applications of cloning technology.
3. Give examples of applications of genetically modified technology.
Modern biotechnology PPT, part 2: Genetically modified technology can purposefully change biological traits
Transgenic technology refers to the use of molecular biology technology to transfer the genes of certain organisms into other species, transform the genetic material of organisms, and transform the organisms with modified genetic materials into the goals that humans need in terms of traits, nutrition, and consumer quality. .
discuss:
1. What are the operating objects of genetically modified technology?
2. What are the tasks of transgenic technology?
3. Why can genetically modified bacteria produce large amounts of human insulin in a short period of time?
Safety of genetically modified foods
Genetically modified food refers to the use of molecular biology methods to transfer the genes of certain organisms to other biological species, causing them to have traits or products that the original species does not have. Foods processed and produced using genetically modified organisms as raw materials are genetically modified foods. Through this technology, humans can obtain food quality that better meets the requirements. It has the advantages of high yield, rich nutrition, and strong disease resistance, but the genetic contamination it may cause is also its obvious shortcoming.
Modern biotechnology PPT, part 3: Cloning technology can copy genetically identical individuals
Cloning is the transliteration of Clone, which means asexual reproduction without the combination of sexual germ cells. Cloning technology is asexual reproduction technology.
"Dolly" is the world's first somatic cell cloned animal, demonstrating that animal cells are as totipotent as plant cells, marking new progress and a major breakthrough in cloning research. After being announced to the world in February 1997, it became the most famous sheep in the world. "Dolly" died of lung infection on February 14, 2003, and his remains were made into specimens and displayed at the National Museum of Scotland in Edinburgh.
Cloning technology benefits mankind
1. Rapidly cultivate excellent crops and livestock;
2. Save rare animals;
3. Prevent and treat diseases and extend life.
Modern biotechnology PPT, part 4: summary
1. Transgenic technology
1. Transgenic technology and pharmaceuticals
2. Transgenic technology and diagnosis and treatment of genetic diseases
3. Transgenic technology and agriculture
2. Cloning technology
1. The essence of cloning is asexual reproduction
2.Clone sheep breeding process:
Enucleation→Nucleation→Fusion→Embryo→Surrogacy
3. The significance of cloning: cultivating excellent varieties; preventing and treating diseases, extending life span; saving endangered animals
Modern biotechnology PPT, part 5: learning and testing
