1. dna replication produces two identical dna molecules, called, which separate during

mitosis.

1. after chromosomes condense, the is the region where the identical dna molecules

are most tightly attached to each other.

1. during mitosis, microtubules attach to chromosomes at the.
2. in dividing cells, most of the cells growth occurs during.
3. the is a cell structure consisting of microtubules, which forms during early mitosis

and plays a role in cell division.

1. during interphase, most of the nucleus is filled with a complex of dna and protein in a dispersed

form called.

1. in most eukaryotes, division of the nucleus is followed by, when the rest of the cell

divides.

1. the are the organizing centers for microtubules involved in separating chromosomes

during mitosis.

Explanation:

1. DNA replication produces two identical DNA molecules, called sister chromatids, which separate during mitosis. Sister chromatids are the result of DNA replication and are held together until mitosis.
2. After chromosomes condense, the centromere is the region where the identical DNA molecules are most tightly attached to each other. The centromere is a constricted region of a chromosome.
3. During mitosis, microtubules attach to chromosomes at the kinetochore. Kinetochores are protein - DNA complexes that allow microtubules to attach to chromosomes.
4. In dividing cells, most of the cell's growth occurs during interphase. Interphase is the phase of the cell cycle where the cell grows and replicates its DNA.
5. The mitotic spindle is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division. The mitotic spindle is responsible for separating chromosomes.
6. During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called chromatin. Chromatin is the material that makes up chromosomes.
7. In most eukaryotes, division of the nucleus is followed by cytokinesis, when the rest of the cell divides. Cytokinesis is the process of dividing the cytoplasm.
8. The centrosomes are the organizing centers for microtubules involved in separating chromosomes during mitosis. Centrosomes help in the formation of the mitotic spindle.
