Why is the controlled timing of gene expression crucial to an organism? It allows for differentiation.
o It allows for specialization.
O It allows for development.
all of the above

All of the above

Differentiation and specialisation are basically the same thing, and are caused because differences in gene expression cause different proteins to be produced that make up different types of cells. This also allows for development- for example as you get older a different genes are expressed to make your hair go gray
