Mitosis Is nuclear division and cyotkinesis. Produces two daughter cells.
ProphaseChromosomes arecoiled together.•Each duplication ofchromosomes are a pairof sister chromatids.•Nucleolus disappears.
Metapha seNuclear membranecompletely disappears.Polar fiber extendcontinually from polesto the center of the cell.Chromosomes moverandomly until theyattach to the pole fibers.Chromosomes are thenaligned with the plate atright angles to thespindle poles.
Anaphas ePaired centromerer ineach chromosomemoves apart.When they separatethey are now onechromosome, calleddaughter cells.Daughter chromosomesmove to opposite endsof the pole.The chromosomesmigrate first to theCentro mere
Telophase Chromosomes are cordoned off into new nuclei in the daughter cells. Polar fibers are lengthening. Nucleus begin to form from opposite poles. Nuclear envelopes are formed from remaining pieces of the parent cell’s nuclear envelope. Chromatin fibers of chromosomes uncoil.
Cytokinesis When the cytoplasm starts to divide. Divides two new nuclei into daughter cells.
Meiosis Meiosis 1: Chromosomes in a diploid cell resegregate. Produces four haploid daughter cells. Meiosis 2: Separates the chromatids producing two daughter cells and each has twenty-three chromosomes.
Prophase 1 and 2 Prophase 1: Chromosomes become visible. Combine to form tetrads. Contain two pairs of chromosomes. Cross over at points. Genetic material Prophase 2: From telophase to prophase 2 without interphase. Nuclear envelope is dissolved and spindle is set up.
Metaphase 1 and 2 Metaphase 1: Trends are arranged across the center by the kinetochores. Metaphase 2: Chromosomes move into the center. There are two chromosomes. Chromatids split off.
Anaphase 1 and 2 Anaphase 1: Chromatids holding the chromosomes together loosens. Homologous chromatids are separated into separate poles. Anaphase 2: Kinetochores moves towards the poles. Splits the sister chromatids.
Telophase 1 and 2 Telophase 1: Chromosomes are moved into opposite poles. Nuclear envelope reforms. Spindle is broken down. Telophase 2: Chromatids concentrate in the poles and nuclear envelope is reformed and the spindle is dissolved again. Cells divide Leaves four haploid cells
