Phases of mitosis Mitosis Biology (article)
Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell’s nucleus is split into two equal sets of chromosomes.
The Process of Meiosis
Meiosis I Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase, which is also called the first gap phase, is the first phase of the interphase and is focused on cell growth.
11.1 The Process of Meiosis Biology for AP® Courses
Microtubules grow from centrosomes placed at opposite poles of the cell. The microtubules move toward the middle of the cell and attach to one of the two fused homologous chromosomes. The microtubules attach at each chromosomes’ kinetochores. With each member of the homologous pair attached to opposite poles of the cell, in the next phase, the.
The Stages of Mitosis and Cell Division
The two pairs of centrioles (formed from the replication of one pair in Interphase) move away from one another toward opposite ends of the cell due to the lengthening of the microtubules that form between them. Polar fibers, which are microtubules that make up the spindle fibers, reach from each cell pole to the cell’s equator.
Overview of the Stages of Meiosis
Chromosomes move to the opposite cell poles. Similar to mitosis, microtubules such as the kinetochore fibers interact to pull the chromosomes to the cell poles. Unlike in mitosis, sister chromatids remain together after the homologous chromosomes move to opposite poles. At the end of anaphase I of meiosis, the cell enters into telophase I.
During metaphase I, the homologous chromosomes are arranged in the center of the cell with the kinetochores facing opposite poles. The homologous pairs orient themselves randomly at the equator. For example, if the two homologous members of chromosome 1 are labeled a and b, then the chromosomes could line up a-b, or b-a.
For each pair, kinetochore microtubules from one pole of the cell are attached to both chromatids of one homolog, while kinetochore microtubules from the other pole of the cell are attached to the chromatids of the other homolog.
The Process of Meiosis
Meiosis I Meiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes.
