Topics in Cell Cycle and Cell Division

1

Introduction to Cell Cycle

  • All organisms start from a single cell and grow through repeated cell divisions
  • Cell cycle is the sequence of events by which a cell duplicates its genome and divides into two daughter cells
  • Cell division involves DNA replication, cell growth, and actual division in a coordinated manner
2

Phases of Cell Cycle

  • Cell cycle has two main phases: Interphase and M Phase (Mitosis)
  • Interphase lasts 95% of cell cycle duration
  • M Phase includes nuclear division and cytoplasmic division
3

Mitosis (M Phase)

  • Mitosis is equational division - chromosome number remains same
  • Occurs in somatic diploid cells (except rare cases like male honey bees)
  • Plants can show mitosis in both haploid and diploid cells
4

Meiosis

  • Meiosis is reduction division - reduces chromosome number by half
  • Occurs in diploid cells destined to form gametes
  • Two sequential divisions: Meiosis I and Meiosis II
