![]() ![]() These sister chromatids become the daughter nuclei's chromosomes. The sister chromatids of each chromosome are joined at the centromere, but their arms remain free.Īnaphase begins with the separation of the sister chromatids. The chromosomes are visible clearly during metaphase. A spindle tube is present that connects the chromosome to the centromere. The spindle tubes form during this stage, and the chromosome is oriented in the centre at the equatorial plate. The phase following prophase is known as metaphase. The chromosome will appear thicker, shorter, and more conspicuous in late prophase, as well as double longitudinally. The chromosome becomes coiled and short, as well as more distinct, during mid-prophase. The chromosome appears as a thin, uncoiled thread in the early prophase stage. The prophase starts after the G2 stage of interphase. This means that the daughter nuclei will have the same chromosome combination as the parent nucleus.įurther, there are four sub-stages under the mitotic phase and they are. It occurs in the absence of recombination. ![]() G2 Phase: The period between the end of DNA synthesis and the start of prophase.ĭuring the mitotic phase, the replicated DNA is separated into two daughter nuclei. S Phase: This is the phase in which DNA synthesis occurs. G1 Phase: This is the period preceding DNA synthesis. When in interphase, it goes through the following phases: The time required to complete the cell cycle varies by species.Ī cell spends a period of its growth in interphase before entering mitosis. The interphase is when DNA is synthesized, and the mitotic phase is when nuclear division occurs. ![]() The cell cycle is divided into two phases is Interphase and Mitotic phase The cell cycle is the period during which one cycle of a cell's division is completed. There is no recombination or segregation during the mitosis stage. The entire mitosis process is made up of only one equational or homotypic division. Mitosis is the process by which plants grow their vegetative parts. This can be found at the stem tip, root tip, and leaf base. Mitosis occurs in plants' somatic organs as well. The chromosome number in the daughter and mother cells is the same, which is known as equational or homotypic division. In size, shape, and chromosome complement, the daughter cells are similar to their mothers' cells. This means that each nucleus divides once during each cell cycle. In each mitotic cell division cycle of mitosis, two daughter cells are formed from a mother cell. This does not function properly if the cells have an excess or a lack of chromosomes. Mitosis' primary goal is to ensure that each daughter cell formed has a complete and perfect set of chromosomes. The mitotic division is a form of reproduction that adds new individuals to the population of single-celled eukaryotes. Throughout its life, mitosis replaces worn out and old cells with new cells. Except for germ cells, most eukaryotic cells divide in such a way that the ploidy or number of chromosomes remains constant.ĭuring the growth and development, an organism's body is filled with cells through the process of mitosis. It is a stage of the cell cycle in which newly formed DNA is separated and two new cells with the same number and type of chromosomes as the parent nucleus are formed.
