Answer: Explanation: During mitotic S phase, DNA replication produces two nearly identical sister chromatids. DNA double-strand breaks that arise after replication has progressed or during the G2 phase can be repaired before cell division occurs (M-phase of the cell cycle).
Q. What stage is called the resting state?
Interphase is the ‘daily living’ or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other “normal” cell functions. Interphase was formerly called the resting phase.

Q. Which cell division phase is known as the resting longest phase?
During interphase, the cell undergoes normal growth processes while also preparing for cell division. It is the longest phase of the cell cycle, cell spends approximately 90% of its time in this phase.
Q. What happens in the mitosis phase?
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
Q. What is the result of inhibition of protein during G2 phase?
Acute inhibition of Wee1 or Wee1/Myt1 causes cells that have already spent some time in G2 phase to quickly enter mitosis. This results in a transient sharp increase in the mitotic cell population (Figures 3F and 4E).
Q. Which stage of cell division occurs after G2 phase?
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Q. Which is the most variable stage of cell cycle?
Introduction to the Cell Cycle G1 is typically the longest and most variable cell-cycle phase. When cells are “born” at cytokinesis, they are roughly half the size they were before mitosis, and during G1, they grow back toward an optimal size.
