Mitosis Quiz
A duplicated chromosome consists of two ______.
chromatids
The centromere is a region in which
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
How many autosomes do humans have?
22
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.
True
Identify the stage of mitosis.
cytonkis
Identify the stage of mitosis.
metaphase
Which of the following occurs during prophase?

All of the following occur during mitosis except the
synthesis of DNA.
Identify the stage of mitosis.
telophase
During telophase ______.
the events of prophase are reversed
Identify the stage of mitosis.
interphase
During metaphase ______.
chromosomes line up at the midline of the cell
