chromatids are attached to one another.

The chromosomes of eukaryotic cells are found in the ______.

nucleus

Cytokinesis usually, but not always, follows mitosis. If a cell completed mitosis but not cytokinesis, the result would be a cell with

two nuclei.

What is a chromatid?

a replicate chromosome

Sister chromatids are joined at the ______.

centromere

Chromosomes first become visible during ________ of mitosis.

prophase

Identify the stage of mitosis.

prophase

The correct sequence of stages of mitosis is ______.

prophase, metaphase, anaphase, telophase

The cell cycle results in the production of ______.

two diploid cells, each with the same amount of genetic material and the same genetic information

The lettered circle in Figure 12.1 shows a diploid nucleus with four chromosomes. There are two pairs of homologous chromosomes, one long and the other short. One haploid set is symbolized as black and the other haploid set is gray. The chromosomes in the unlettered circle have not yet replicated. Choose the correct chromosomal conditions for the following stages. at prometaphase of mitosis

B

B

The questions below refer to the following terms. Each term may be used once, more than once, or not at all. A-telophase B-anaphase C-prometaphase D-metaphase E-prophase Centromeres uncouple, sister chromatids are separated, and the two new chromosomes move to opposite poles of the cell.

B

The questions below refer to the following terms. Each term may be used once, more than once, or not at all. A-telophase B-anaphase C-prometaphase D-metaphase E-prophase Two centrosomes are arranged at opposite poles of the cell.

C

Which of these events occurs during anaphase?

Centromeres divide

The lettered circle in Figure 12.1 shows a diploid nucleus with four chromosomes. There are two pairs of homologous chromosomes, one long and the other short. One haploid set is symbolized as black and the other haploid set is gray. The chromosomes in the unlettered circle have not yet replicated. Choose the correct chromosomal conditions for the following stages. one daughter nucleus at telophase of mitosis

E

The questions below refer to the following terms. Each term may be used once, more than once, or not at all. A-telophase B-anaphase C-prometaphase D-metaphase E-prophase This is the longest of the mitotic stages.

E

When the cell is resting from division it is said to be in interphase.

False

Which of the following occurs during interphase?

Sister chromatids separate

How do the daughter cells at the end of mitosis and cytokinesis compare with their parent cell when it was in G1 of the cell cycle?

The daughter cells have the same number of chromosomes and the same amount of DNA.

Anaphase is the stage of cell division when the cleavage furrow first appears.
