PERFORMANCE TASK #1: THE CELL CYCLE Direction: Label the diagram below with the following labels: Anaphase Cell division (M Phase) Cytokinesis G1 – cell grows G2 – prepares for mitosis S- DNA replication Metaphase Prophase Telophase Interphase Mitosis Then on the diagram, lightly color the G1 phase GREEN, the S phase dark BLUE, the G2 phase light BLUE, and the stages of mitosis VIOLET. Color the arrows indicating all of the interphases in RED. Color the part of the arrow indicating mitosis ORANGE and the part of the arrow indicating cytokinesis YELLOW.

A B number of chromsomes per cell C 100 90 D 80 A bar graph comparing the number of chromosomes at different stages of cell division. 20 Which of the following best explains the change in the number of chromosomes between metaphase and anaphase? prophase metaphase anaphase telophase cytokinesis stage of cell division New chromosomes formed during prophase are doubled during anaphase. DNA replication occurs between metaphase and anaphase, doubling the number of chromosomes. During metaphase, a cell contains identical copies of each chromosome, and then trans- forms into sister chromatids. During anaphase, the chromatids are separated, each becoming independent chromo- somes in its respective new cell
