(d) Cells are treated with a compound that prevents the inactivation of kinase D . Researchers claim that Brec-WT cells treated with this compound will stimulate blood vessel-forming cell division to the same degree as Brec-MUT cells do in the absence of B . Based on the information provided, provide reasoning to support their claim.
