A student says that mitotic daughter cells must always look and behave exactly the same because they are genetically identical. Which response is most accurate?
A
Mitosis always changes the DNA sequence, so identical daughter cells never occur.
B
Mitosis can preserve DNA sequence, but daughter cells may later differ in appearance or function because of gene regulation and environment.
C
Mitosis produces gametes, so appearance and function are controlled only by fertilization.
D
Mitosis eliminates gene expression differences by forcing every cell to make the same proteins forever.
