Document Summary
*common evolutionary history for all organisms = most profound observation in biology. Genetic info, copied and stored and used in the same way. Cells can only arise from other cells. Can trace back to 4 billion years. Humans are made of 4 trillion cells. Over 200 types of cells, still discovering same genetic information in every cell even though they are different types there are specific genes that turn off/on in different types of cells (transcription) 8 cell embryo is pluripotent capable of forming into any tissue. Can remove one of those 8 cells and use for anything stem cell. Induced pluripotent stem cells (ips) take adult cells and reverse to pluripotent stem cell. Use your own cells = more success, you reject other people"s cells. Diverged from chips 5 million years ago but still 98% of genetic identity is the. Rather weak structure, without membrane you cannot have a cell. Humans are more prokaryotic cells than eukaryotic cells.
