Cell Cycle Interphase Mitosis

Interphase Cell normally functioning Phase cell is in most of the time Cell Grows and DNA is replicated

Mitosis-PMAT Prophase-Prepare Metaphase-Middle Anaphase-Apart Telophase-THE END DO NOT WRITE WHAT IS ON THIS SLIDE!

Prophase-PREPARE Cell PREPARES to divide Centrioles get into place Chromosomes condense Nuclear envelope dissolves

Metaphase-MIDDLE Chromosomes line up in the MIDDLE of the cell

Anaphase-APART Chromosomes are pulled APART by the centrioles and spindle fibers

Telophase-THE END The chromosomes are at each end of the cell and nuclear envelops form The cell divides in two-Cytokinesis THE END

What does PMAT stand for? Prophase  Metaphase  Anaphase  Telophase Prepare  Middle  Apart  THE END

Mitosis

Controls on Cell Division Cells only divide when growth is needed Cyclins are proteins that regulate the timing of the cell cycle

Uncontrolled Cell Growth When cells lose the ability to control growth it results in a mass of cells called a tumor. Benign tumors –Do not metastasize (spread) Malignant tumors-Cancer –Metastasize

Skin Cancer
