![]() ![]() This is the phase through which the DNA is copied in order to produce the daughter cells. Interphase is followed by the M phase (mitotic phase). G2 phase - This is the second gap phase (first gap phase being G1) characterized by continued cell growth, production of proteins and organelles as well as content re-organization to prepare the cell for mitosis.S phase - This phase is characterized by the development of the DNA molecule in the nucleus as well as the duplication of the centrosome (this is the microtubule structure involved in separating the DNA during mitosis).G1 phase - The cell grows in size with an increase in the number of organelles as well as the development of various molecular building blocks required for mitosis.The cell, therefore, undergoes several phases in interphase in order to be ready for mitosis. Once a new cell is formed through mitosis, it has to be ready in order to undergo mitosis and produce new daughter cells as the cycle continues. Rather, it is the preparation phase that precedes mitosis. Interphase - This is not necessarily one of the main stages of mitosis. There are four types of binary fission that include: * In any of the 4 stages, issues may arise resulting in various abnormalities * Movement of chromosome strands to the opposite poles of the cell requires energy * Organelles such as mitochondria also use this method of cell division (binary fission) to increase in number Ultimately, the cell splits along the middle (at the septum) dividing the cell into two new daughter cells, each of which contains nuclear material and other cell organelles. ![]()
