Before a cell goes through cell division (mitosis), it must grow and make a copy of its DNA which is termed as an Inter-phase.
Explanation:
Some tasks must be carried out by the cells before they undergo division: The cell must grow, it must copy the genetic material (DNA) present in it, and divide into two daughter cells. These steps carried out by cells are termed as cell cycle.
Cells that contains a nucleus or Eukaryota cells, there are two major phases called interphase and the mitotic (M) phase. that comprises the cell cycle.
In inter-phase, growth of the cell and making a copy of its DNA is carried out.
In mitotic (M) phase, the cell separation of the DNA in the cell into two sets and division of its cytoplasm takes place resulting in the formation of two new cells.
Before the start of mitosis, the cell is found in a period called interphase. During this step, the cell has its DNA duplicated and the production of proteins takes place.
Interphase is made up of the G1 phase (cell growth), followed by the S phase (DNA synthesis), followed by the G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is composed of mitosis and cytokinesis and leads to the formation of two daughter cells.
After interphase, cell division begins. Didactically, mitosis is usually divided into four phases:
With this information, we can conclude that before the start of mitosis, the cell is in a period called interphase. In this stage, the cell has its DNA duplicated and the production of proteins occurs.
