Is a type of pollination that occurs when pollen from one flower pollinates a flower on a different plant

Cross pollination.

Explanation:

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
