1. DNA structure terminology Chromatin- unwound DNA (loose) Copied Sister chromatids- two identical copies of DNA (loose) Coiled and Connected Chromosomes- two coiled, identical copies of DNA connected to each other (tight)

5. Which cell types undergo Mitosis? Prokaryotes: ______Eukaryotes: _____ Stages of Mitosis (PMAT) 1. Prophase- chromosomes condense, nuclear envelope breaks apart 2. Metaphase- chromosomes line up in center of cell 3. Anaphase- chromosomes split apart to opposite ends of cell 4. Telophase- nuclear envelope surrounds chromosomes

8. Division of Prokaryotes

9. Cell Cycle: When does division occur? 90% cell Life

10. Cell Cycle Cell spends majority of life (90%) in Interphase (G1, S and G2) G1: cell growth, cell enlarges in size, continues to make and recycle organelles, etc. S: cell’s DNA is copied G2: cell prepares for nucleus to divide M: cell divides into two daughter cells Cytokinesis: cytoplasm and new cell membrane/ cell wall are made
