Cellular division Mitosis - exact duplication of nuclear material; 0. Two daughter cells are identical to parent. Cells life cycle 5 phases IPMAT interphase, prophase, metaphase, anaphase, telophase Interphase - 3 parts G1- normal growth and development S- where chromosomes replicate*** G2- cell readies for division Chromosome duplication When chromosomes duplicate, Copies remain attached at the centromere Each copy is called a chromatid . Mitosis phases 1) Prophase 2) Metaphase 3) Anaphase 4) Telophase Prophase: 1) Chromosomes shorten and thicken

Anaphase Sister chromatids are pulled apart by the shortening of the spindle fibers. Once the chromatids are separated, They are now considered individual chromosomes. Telophase Nuclear material thins out. Nuclear envelope reappears . Cytokinesis Cytokinesis begins at the end of anaphase and continues through telophase. Cleavage furrow- animal cells...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
