How does the human part affect cognition? A stem cell for example is before it "decides" to be a specific cell right? If that is the case in terms of embryo development, then how do they coax only specific cells in embryos to only express themselves in parts of the body excluding the brain. Complicated but I really am not understanding some basic principles here.
- HeadsUpHigh 7y agoYes you are missing basic parts. There are certain genes that produce proteins that then bind to other control areas of the DNA that affect how much other genes are expressed. These last genes translate to proteins that make e.g. a pancreatic cell what it is. But this is a tree of increased specialization on which embryonic stem cells become e.g. blood stem cells which then specialize to rbc, white platelet producers.
