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

The DNA in our cells contains the blueprints for many different cells, but only some of the instructions are “expressed” at any given time. The mechanisms for this are extremely complex but by the expression of certain genes different cells and organs are grown from the same master instructions.
