  1. BIOLOGY-APCELL-MITOSIS Mr. Swartz September 25, 2011

  2. Interphase VISUAL REPRESENTATION Points to consider • DNA has replicated, but has not formed the condensed structure of chromosome. • Chromosomes remain as loosely coiled chromatin. • Nuclear membrane still intact to protect the DNA molecules from undergoing mutation. Photograph taken from http://library.thinkquest.org/C0118084/Gene/Chromosomal_Inheritance/StagesMitosis.htm

  3. Prophase VISUAL REPRESENTATION Points to consider • The DNA molecules progressively shorten and condense by coiling, to form chromosomes. • The nuclear membrane and nucleolus are no longer visible. • The spindle apparatus has migrated to opposite poles of the cell. Photograph taken from http://library.thinkquest.org/C0118084/Gene/Chromosomal_Inheritance/StagesMitosis.htm

  4. Metaphase VISUAL REPRESENTATION Points to consider • The spindle fibers attach themselves to the centromeres of the chromosomes • The fibers align the chromosomes at the equatorial plate. Photograph taken from http://library.thinkquest.org/C0118084/Gene/Chromosomal_Inheritance/StagesMitosis.htm

  5. Anaphase and Telophase VISUAL REPRESENTATION Points to consider • The spindle fibers shorten and the centromeresplits. • The chromosomes reach the poles of their respective spindles. • Nuclear envelope reform before the chromosomes uncoil. • The spindle fibers disintegrate.
