Regarding Genome Sequences and Organismal Development,it Is Important to Remember

Regarding genome sequences and organismal development,it is important to remember that

A) development occurs almost exactly the same way in closely related species.
B) development takes longer in some species than in others,and this time factor is important.
C) gene sequence within a chromosome determines the timing of the gene expression.
D) timing plays an important part in genome sequencing.
E) changing the timing of gene expression can have dramatic changes in development.
