List the six phases of the cell cycle in order. ____________ condenses to form chromosomes. ___________ is the stage (not phase) during which the cell’s nucleus divides into two new nuclei. The stage of the cell cycle when DNA replication occurs is called __________.

Answers… List the three stages of the cell cycle. Interphase Mitosis Cytokinesis List the six phases of the cell cycle. Mitosis: Prophase Mitosis: Metaphase Mitosis: Anaphase Mitosis: Telophase

Answers… Chromatin condenses to form chromosomes. Mitosis is the stage (not phase) during which the cell’s nucleus divides into two new nuclei. The stage of the cell cycle when DNA replication occurs is called Interphase.

11/15 On a blank piece of paper, answer the following (yes, you WILL hand this in): List the six phases of the cell cycle in order and briefly explain what is happening in each phase.

Answers Interphase – The cell grows and makes a copy of its DNA. Mitosis: Prophase – The chromatin condenses to form chromosomes. Mitosis: Metaphase – The chromosomes line-up across the center of the cell. Mitosis: Anaphase – The centromeres split and the chromatids move to opposite ends of the cell. Mitosis: Telophase – Two new nuclear envelopes form. Cytokinesis – The cytoplasm splits and two new daughter cells are formed.
