Ap bio mitosis phases

Interphase G1

growing and prepping

Interphase S

Copying of DNA

Interphase G2

Finish growth preperation and checking

6 phases

Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis

Prophase

Nucleus disassembles, chromosomes condense, centrioes organize spindle fibers and migrate to opposite poles of cell

Metaphase

chromosomes (sister chromatids) line up at metaphase plate, Microtubule spindle fibers attach to kinetochores

Anaphase

Centromere divides, sister chromatids migrate to sides, kinetochores disassemble microtubules

Telophase

'reset' phase; nucleus reassembles and chromosomes decondense

Cytokinesis

Microfilaments cinch the cell into two

Cleavage Furrow

2 cells after cytokinesis

Actin

Microfilament in cytokinesis

3 reasons for cell division

growth (GH), repair (PDGF), reproduction

Mitosis

Copying of nucleus

Binary Fission

Bacteria use and copying of mitochondria and chloroplasts

chromatin

DNA in loosest form

chromosomes

DNA condensed
