Differentiation: Definition |
- cells develop in different ways - differentiation depends on gene expression which is regulated mostly during transcription |
|
|
Multicellular Organisms Differentiate |
- multicellular organisms differentiate to carry out specialized functions by expressing some of their genes but not others Advantages: - cells can differentiate to be more efficient unlike unicellular organisms who have to perform all functions within one cell |
|
|
Genes in Multicellular Organisms |
- every cell in a multicellular organism contains all the genes of that organism - however, genes that are activated vary from cell to cell - different genes are activated for specific functions |
|
|
Stem Cells and Differentiation |
- stem cells have the ability to produce a wide range of cells - pluripotent - retain their ability to divide and produce different cells by cell division and differentiation Example: one type of stem cells in the bone marrow produce a variety of red and white blood cells |
