INTRODUCTION The most basic characteristic of life Rudolf Virchow “All cells come from cell” What is cell cycle? Cell cycle is define as the series of changes in cell Cell cycle consist of two phases Interphase Mitotic phase INTERPHASE Interphase is further divided into three phases G1 phase (first gap) S phase (synthesis) G2 phase(second gap) MITOSIS In 1880s, a German biologist WALTER FLEMMING observed series of changes in dividing cell…. Four Mitotic Stages Prophase Metaphase Anaphase Telophase Prophase Metaphase Anaphase TELOPHASE Reversal of prophase New nuclear envelope form Chromosomes unfold back into chromatin Cytokinesis REVIEW OF MITOSIS Used for growth and repair Produce two new cells identical to the original cell Cells are diploid (2n)

2.  The most basic characteristic of life
 Rudolf Virchow
 “All cells come from cell”

3.  Cell cycle is define as the series of changes in
cell
 Cell cycle consist of two phases
I. Interphase
II.Mitotic phase

4. Interphase is further divided into three
phases
i. G1 phase (first gap)
ii. S phase (synthesis)
iii. G2 phase(second gap)

5. In 1880s, a German biologist WALTER
FLEMMING observed series of changes in
dividing cell….
