  1. Interphase: is the longest phase of cell cycle, overall takes 16 hours for a growing mammalian cell. It consists three stages:
    1. G1 (Gap-1) phase: It is presynthesis stage, in which cell prepares for DNA replication, which takes 5 hours. Due to which chromosomes are replicated.
    2. S (synthetic) phase: It is synthetic phase, in which DNA replication takes place. This phase over in 7 hours.
    3. G2 (Gap-2) phase: It is post synthetic stage, where cell gets ready for cell division or else we can say for Mitotic phase. This phase completes in 3 hours.
  2. Interkinesis is also known as interphase II that occurs during meiosis, between meiosis I and meiosis II.
  3. No DNA replication takes place during this phase, i.e. this phase lacks S-phase.
