write the 3 phases of interphases
Answers
Answer:
The cell cycle has three phases that must occur before mitosis, or cell division, happens. These three phases are collectively known as interphase. They are G1, S, and G2. The G stands for gap and the S stands for synthesis.
Answer:
3 phases of interphase are as follows :
1) G1 -phase I. e. first growth phase -
in this phase cell growth occurs,
normal cell function,organelle duplication,
RNA and proteins are synthesized in this phase
2)S-phase I. e synthesis phase-
in this phase DNA is synthesized , so that amount of DNA per cell doubles .
synthesis of histone proteins also occurs in this phase.
3)G2-phase I. e second growth phase -
in this phase nucleus increases in volume .
metabolic activities essential for cell division occurs during this phase .
proteins are also synthesized .
