Hey Mate!!!!
Here is the answer
==================
Phases of Cell Cycle
====================
The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells. The cell cycle has two major phases: interphase and the mitotic phase
Interphase
===========
During interphase, the cell undergoes normal growth processes while also preparing for cell division. In order for a cell to move from interphase into the mitotic phase, many internal and external conditions must be met. The three stages of interphase are called G1, S, and G2.
The Mitotic Phase
=============××××
The mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and move into two new, identical daughter cells. The first portion of the mitotic phase is called karyokinesis, or nuclear division. The second portion of the mitotic phase, called cytokinesis, is the physical separation of the cytoplasmic components into the two daughter cells.
Hope it helps you out

Cell cycle is the cycle that a typical cell goes through. It has three distinct phases, interphase, mitosis, and cytokineses.
◆Interphase: This is when the cell is going through its normal functions, whatever it may be. This is also when the cell grows, replicates its DNA, and copies all its organelles to prepare itself for cell division.
◆Mitosis: The division of the nucleus, it has 4 common phases, prophase, metaphase, anaphase and telophase. In mitosis, the nucleus and nucleolus first dissolves while the cell's chromatins are condensed and coiled to form chromosomes which are aligned and split into opposite sides of the cell where it will form two separate nucleus.
◆Cytokineses: The division of the cytoplasm, this is when the microfilaments form a cleavage furrow which divides the large cell into two daughter cells. With cytokineses finished, the cell completes its cell cycle.
In a typical cell cycle, the cell is in interphase approximately 90% of the times, concentrating on its function.
Some cells are in G0 phases, where they are constantly in interphase. An example of this is the neuron, which does not undergo mitosis.
