Stages of mitosisInterphase :• Cell grows and caries out normal cell processes• DNA replicatesProphase :• Cell chromatin tightens into chromosomes (condenses).• Nucleus disappearsMetaphase :• Shortest stage• Chromosomes attach to spindle apparatus and align alongthe equator of the cell.Anaphase:• Microtubules shortens moving the chromosomes to oppositepoles.Telophase :• Nucleuses reapers• Chromosomes recondense
MeiosisMEIOSIS 1Interphase:• Chromosomes replicate• Chromatin condensesProphase 1:• Pairing of omogous chromosomes occurs each chromosome concicts of twochromatids• The neuclear envolpe breaks down• Spindles formMetaphase 1:• Homologous chromosomes line up at the equater• Chromosome centromers attach to spindle fibers.Anaphase 1:• Homologous chromosomes separate and move to opposite poles of the cell.Telophase 1:• The spindles break down chromosomes uncoil and form two nuclei,• The cell divides.MEIOSIS 11Prophase 11:• Chrommosomes condense.• Spindles from in each new cell.• Spindle fibers attach to chromosomesMetaphase 11;• Centromeres of chromosomes line uprandomly at the equator of each cell.Anaphase 11:• Centomeres split• Sister chromatids seprate and move toopposite polesTelephase 11:• Four nuclie from around chromosomes• Spindles break down• Cells divide
