Learning Target 6: The Main Events of the Cell Cycle :

Learning Target 6: The Main Events of the Cell Cycle Brittany Rossie and Ethan Williams

Interphase:

Interphase One cell division after another Cell divides and forms 2 daughter cells 4 stages- G1, S, G2, M G1 and G2 stand for gaps in between the S and M phases

G1,S,G2,:

G1,S,G2, G1- Cells grow and synthesize new proteins and organelles S- Chromosomes replicated, DNA molecules and key proteins synthesized G2- Cell replication is completed, organelles and molecules produced, Ready for mitosis

Mitosis:

Mitosis 5 phases Prophase- Chromosomes become shorter and thicker, spindle fibers form Metaphase- Chromosomes line up, spindle fibers reach for chromatids Anaphase- Chromatids separate at centromere , and are pulled by spindle fibers Telophase - 2 groups of chromosomes reach opposite ends of cell, nuclear envelope produced, spindle fibers disapper

Cytokinesis:

Cytokinesis C Phase Cells cytoplasm divides Forms 2 genetically identical daughter cells Process starts over
