Regulation of Gene Action
... The basis of cell differentiation is gene regulation: different sets of genes are turned on and off in different cells. (There are other mechanisms as well but this is our focus.) E.g. globin genes are expressed only in erythroblasts and are turned off in muscle cells. Myosin genes are on in muscle ...
