Overview

Cell division is the basis of growth, repair, reproduction, and continuity of life. The cell cycle is the period from the end of one division of a cell to the end of the next division. It has two main phases: interphase and M-phase. Interphase is an active growth and preparation stage, while M-phase

Key Concepts

Cell theory states that new cells

Cell theory states that new cells originate from the division of pre-existing cells. It was proposed by Schleiden and Schwann and later supported by N

The cell cycle is the period

The cell cycle is the period from the end of one division of a cell to the end of the next division. It includes interphase and M-phase.

C

C-value is the amount of DNA, in picograms, contained within a haploid nucleus or half the amount in a diploid somatic cell. In diploids, it may be us

Interphase is the active growth phase

Interphase is the active growth phase between two divisions. It is not a resting stage. It includes G1, S, and G2 phases.

G1 phase is the longest interphase

G1 phase is the longest interphase sub-phase. It lies between mitosis and DNA replication and is the period of maximum cell growth, with no change in

Learning Objectives

  • Understand the meaning and phases of the cell cycle
  • Explain interphase and its sub-phases G1, S, and G2
  • Describe G0 as the quiescent stage of non-dividing cells
  • Explain mitosis as equational division and its stages
  • Describe meiosis I and meiosis II and their differences from mitosis
