Document Summary
Previous lecture: you can inherit patterns of gene regulation from your parents. Some of your cells regulate gene expression by making genetic changes. But most of the changes are not genetic. A change in regulation that persists beyond the initial condition: epigenetics. Example: x inactivation this persists well past early embryogenesis. Regulation of gene expression affects the possibility for specialization. Or maybe evolution is just very strong inside no longer possess flagella single cells (undifferentiated cells) Volvocine algae provides a productive model system . Extra cellular matrix largely modified proteins surrounds a group of. Volvox consists of smaller somatic cells and a few reproductive cells cells. Each of the single cells are immortal they just continue to divide and never. With multicellular cells, all of the cells have to agree to die at a certain point they are mortal collective suicide. Division of labour and a division of death die because they never need to.
