Cell Division & Mitosis

The Cell Cycle The Cell Cycle is the process your cells go through as they LIVE and DIVIDE.

The Four Phases of the Cell Cycle Cell Division Rapid cell growth Chromosomes duplicate INTERPHASE Growth; preparing to divide …REPEAT

When the cell prepares to divide, it makes a copy of its chromosomes Each chromosome and its copy are called sister chromatids The process of cell division has TWO parts: Mitosis- active division Cytokinesis- cell splits into 2 Let’s take a closer look…

Interphase Cell growth Regular cell functions Majority of cell cycle is in this phase

Prophase DNA condenses and chromosomes are visible Nuclear membrane dissolves Centrioles and spindle form

Metaphase Chromosomes line up along the METAPHASE PLATE Held in place by spindle

Anaphase Sister chromatids are pulled apart Move to opposite poles

Telophase Spindle disappears Nuclear membrane formed Chromatids decondense

Cytokinesis 2 daughter cells are formed!
