Explain why the process of cell differentiation occurs.

Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression occurs because of certain signals in your body, both inside and outside of your cells. Cell differentiation occurs during multiple stages of development.

this goes by cell size cell shape,membrane potential and metabolic activity. these changes are actually because of modifications in gene expression

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion
