Cell Cycle – Interphase G₂

Description:

The changes in a cell that occurs during the G₂ phase of interphase are as follows −

• Known as G₂ - phase or Gap –II or Post-synthetic or Pre-mitotic phase or second growth phase.
• Synthesis of DNA stops.
• Synthesis of spindle proteins.
• Formation of three types of RNA namely t-RNA, r-RNA and m-RNA.
• Synthesis and storage of ATP molecules.
• Duplication of mitochondria and plastids.
• Damaged DNA is repaired in this stage.
