What are the steps of cell growth?
Cell growth can refer to the expansion of one cell because it is preparing for the division or expansion of the population of cells that grows through cell division. Both processes are part of the cell cycle. Many events occur when the cell is preparing for division and eventually division into two identical daughter cells. After this period of rest, which varies depending on the type of cell, the cell enters the intermediate part of the cell cycle. It also develops another cytoplasm that will need to divide into two full -size cells at the end of the process. During the next host in the intermediate district, the DNA is unpacked and replicated and creates two sets of chromosomes. In gap 2 Mezifase, the cell is checked to make sure the DNA has been correctly replicated and continues to grow until it is large enough to split.
After the meziphase is the next step in cell growth mitosis that is divided into four SAmoldy steps. During the mitosis, the cell itself ceases to grow and creates another protein and the process of distributing replicated chromosomes on the opposite side of the nucleus begins. In the first step, called profasses, chromosomes condense and the spindle fibers move to the opposite poles in the cell.
The second step is a metaphase in which the chromosomes are leveled along the central axis of the cell. The spindle fibers are attached to chromosome duplicates, while in the anaphase each set of chromosomes begins to download from the center. Chromomas are completing their move to the opposite side of the cell during Telophase, the last phase of mitosis. Chromosomes then unfold and a nuclear membrane appears around each set of chromosomes.
The final phase of cell growth includes the actual division of one cell into two daughter cells. In this process, known as cytokinesis, the cytoplasm itself is divided. This increases the population of cells in the area and sends two daughter cells back to the resting phase until the body informs the cells, that they need to grow and divide again.
