Why does dna copy itself during the cell cycle? a. to share proteins b. so each daughter cells has the same dna c. to make more cells d. so the cell will not have mutations and develop cancer?

Well the whole point of the cell cycle is to make more cells so it could be C, but it also wants the daughter cell to have the same AMOUNT of DNA, not the exact type (in meiosis) so B may be right, but most likely it is C

Were is the question
