Mitosis is divided into four major phases: prophase, metaphase, anaphase, and telophase. Careful regulation of the cell division program is crucial for proper cell growth, development, and gametogenesis.
9 Σεπ 2024 · Mitosis is a process of cell duplication, in which one cell divides into two genetically identical daughter cells. In the various stages of mitosis, the cell’s chromosomes are copied and then distributed equally between the two new nuclei of the daughter cells.
The first step involves RNA polymerase, an enzyme that unwinds and unzips the double helix to access a protein-coding gene. The gene's DNA sequence is used as the template for transcribing an RNA copy of that gene, which the polymerase assembles from a chain of nucleotides.
The stages of cell division oversee the separation of identical genetic material into two new nuclei, followed by the division of the cytoplasm. Mitosis is divided into five stages—prophase, prometaphase, metaphase, anaphase, and telophase—visualized here by light microscopy with fluorescence.
30 Ιαν 2023 · Process of cell division (mitosis) During cell division, the contents of the parent cell are copied and divided between the two daughter cells. Before this can happen, the nucleus of the parent cell needs to divide.
Mitosis (/ m aɪ ˈ t oʊ s ɪ s /) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis is an equational division which gives rise to genetically identical cells in which the total number of chromosomes is maintained. [1]
