if all the genes in our body are the same how come we have so many different cell types that perform different functions?

Question

if all the genes in our body are the same how come we have so many different cell types that perform different functions?

Answer 1

Basically the different cells only use the parts of the DNA that they need. Genes that aren’t used by a particular cell are essentially turned off so they aren’t used to assemble proteins.
