1. dna replication produces two identical dna molecules, called sister chromatid(s), which separate during mitosis.2. after chromosomes condense, the centromere(s) is the region where the identical dna molecules are most tightly attached to each other.3. during mitosis, microtubules attach to chromosomes at the .4. in dividing cells, most of the cell's growth occurs during .5. the is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division.6. during interphase, most of the nucleus is filled with a complex of dna and protein in a dispersed form called .7. in most eukaryotes, division of the nucleus is followed by , when the rest of the cell divides.8. the are the organizing centers for microtubules involved in separating chromosomes during mitosis.
