ESSENTIAL QUESTIONS:
UNDERSTANDINGS / APPLICATIONS / NATURE OF SCIENCE
DIFFERENTIATION
1.1.U4 Multicellular organisms have properties that emerge due to the interaction of their cellular components.
1.1.U5: Specialized tissues can develop by cell differentiation in multicellular organisms
1.1.U6: Differentiation involves the expressions of some genes and not others in a cell’s genome.
STEM CELLS
1.1.U7: The capacity of stem cells to divide and differentiate along different pathways is necessary in embryonic development and also makes stem cells suitable for therapeutic uses.
1.1.A3: Use of stem cells to treat Stargardt’s disease and one other named condition
1.1.A4: Ethics of the therapeutic use of stem cells from specially created embryos, from the umbilical cord blood of a newborn baby and from an adult’s own tissues
1.1.NOS2: Ethical implications of research- research involving stems cells in growing in importance and raises ethical issues
CLONING
3.5.U5: Clones are groups of genetically identical organisms, derived from a single original parent cell
3.5.U7: Animals can be cloned at the embryo stage by breaking up the embryo into more than one group of cells.
3.5.U8: Methods have been developed for cloning adult animals using differentiated cells.
3.5.A4: Production of cloned embryos produced by somatic-cell nuclear transfer.
- What are stem cells, and why are they important?
- What are the unique properties of all stem cells?
- How does differentiation lead to different structure?
- What are the two types of stem cells and what are their potential uses?
