Bio Assignment #7

Arrange the phases of mitotic cell division in chronological order. Begin the series with the first step after interphase.

1) Interphase 2) Prophase 3) Metaphase 4) Anaphase 5) Telophase 6) cytokinesis

Suppose these two chromosomes are found in a cell nucleus during prophase. What is the relationship between chromatids A, B, C, and D? Select all that apply.

A is identical to B ; C is identical to D

Fill in the concept map below with the appropriate phases of interphase and mitosis. Labels can be used more than once or not at all. Each answer dock can receive multiple labels.

DNA - Condenses into visible chromosomes during ---> Prophase. DNA - is encircled by two separate nuclei in one cell during ---> Telophase. Replication - occurs during ---> S phase. Mitosis - is divided into ---> Prophase, Metaphase, Anaphase, and Telophase.

Mitosis includes interphase and cytokinesis.

False

When in the cell cycle does DNA replication occur?

Interphase

Match each description with the correct phase of the cell cycle.

Metaphase = Chromosomes align at the equator of the cell Prophase = Chromosomes are continue to condense and become visible Telophase = Nuclear envelope forms Interphase = DNA replicates Cytokinesis = The cytoplasm divides Anaphase = Centromere splits and sister chromatids moves to opposite ends of the cell

Select the stages of the cell cycle during which each chromosome consists of two chromatids joined at the centromere.

Prophase, Metaphase, late interphase

Sister chromatids separate during anaphase.

True
