Genetic Engineering And Cell Division
Akopọ
Every person with type 1 diabetes who injects insulin today relies on bacteria that have been given a human gene. Genetic engineering lets scientists move a single useful gene between completely different species, turning bacteria into miniature insulin factories and plants into sources of vaccine proteins.
In this lesson you will learn how a gene is cut out, inserted into a vector and used to reprogramme an organism, follow the four stages of mitosis that let a single fertilised egg become a fully grown human body, and weigh up the promise and the ethical difficulties of using stem cells in medicine.
Awọn Afojusun
- Outline principles of genetic engineering, including the production of genetically modified bacteria to produce human insulin, and the production of genetically modified plants to produce vaccines and to improve health
- Understand that mitosis occurs during growth, repair, cloning and asexual reproduction
- Know the four main stages of mitosis: prophase, metaphase, anaphase and telophase, which results in the production of two genetically identical diploid daughter cells
- Know that there are different types of stem cells, including embryonic and adult stem cells that have the ability to develop into other body cells
- Describe the advantages, disadvantages and ethics in the research and use of embryonic and adult stem cells
