Mitosis consists of four main stages: Prophase, Metaphase, Anaphase and Telephase. Prophase: Chromosomes condense and become visible, move towards equator of nucleus Metaphse:Chromosomes align at the equator of the cell, nuclear membrane breaks down, spindle fibres form Anaphase: centromeres split to form two identical chromatids, single-stranded chromosomes (chromatid) are drawn to opposite sides of the cell by the spindle fibres Telephase: spindle fibres dissolve, new nuclear membranes form around new nucleus There are also two other stages involved in Mitosis Cytokinesis: division of the cytoplasm (seperating the two daughter cells to form two new cells) Interphase: resting stage for cell growth, replicate DNA and organelles, each single-stranded chromosome replicates to form a double-stranded chromosome.
What else can I help you with?
This is longest of the mitotic stages?
The longest mitotic stage is typically prophase, where the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form. Prophase is a crucial stage for preparing the cell for division by ensuring that each daughter cell receives the correct number of chromosomes.
The mitotic phase characterized by the formation of two new nuclei and separation of the daughter cells is?
cytokinesis
How does pro-phase look different from inter-phase?
an interphase is the stage of a cell between two successive mitotic or meiotic divisions an a prophase is the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.
What is the longest stage in mitosis?
The longest stage in mitosis is typically prophase, as it involves the condensation of chromatin into visible chromosomes, the breakdown of the nuclear envelope, and the organization of the mitotic spindle apparatus.
If cells in the interphase are subjected to colchicine at which stage will mitosis stop?
Colchicine will stop mitosis at the metaphase stage. Colchicine disrupts the formation of the mitotic spindle fibers, which are critical for separating the replicated chromosomes during mitosis. As a result, cells treated with colchicine will not be able to progress past the metaphase stage of mitosis.
Prophase occurs during which stage of the cell cycle?
Prophase occurs during the first stage of the cell cycle, which is the mitotic phase. It is characterized by the condensation of chromatin into visible chromosomes, the disintegration of the nuclear envelope, and the formation of the mitotic spindle.
What is intermediate mitotic organisation?
Intermediate mitotic organization refers to the stage of mitosis where the chromosomes have become condensed and aligned along the equatorial plane of the cell. This stage occurs after prophase and metaphase and before anaphase in the cell cycle. At this stage, the cell is preparing to separate the chromatids and distribute them to the daughter cells.
Give the two major divisions of mitotic cell division?
The two major divisions of mitotic cell division are the first stage, known as karyokinesis, where the nucleus divides, and the second stage, cytokinesis, where the cytoplasm splits to form two daughter cells.
Why is the nucleus start to disappear in early stage of mitosis?
so that the mitotic spindel can form and the chromosomes can get attched to the spindel
This is longest of the mitotic stages?
The longest mitotic stage is typically prophase, where the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form. Prophase is a crucial stage for preparing the cell for division by ensuring that each daughter cell receives the correct number of chromosomes.
The mitotic phase characterized by the formation of two new nuclei and separation of the daughter cells is?
cytokinesis
In what mitotic stage does the cytoplasm divide?
The stage of mitosis in which cytoplasm divides is called cytokinesis. This stage is often simply called cell division. In this stage two daughter cells are formed.
How does pro-phase look different from inter-phase?
an interphase is the stage of a cell between two successive mitotic or meiotic divisions an a prophase is the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.
What is the term for the retention of larval or other juvenile characteristics into the adult stage?
The term for the retention of larval or other juvenile characteristics into the adult stage is neoteny. This phenomenon can result in adult organisms retaining features like gills or immature reproductive organs.
What is the longest stage in mitosis?
The longest stage in mitosis is typically prophase, as it involves the condensation of chromatin into visible chromosomes, the breakdown of the nuclear envelope, and the organization of the mitotic spindle apparatus.
An embroy during the late stage of development?
During the late stage of development, the embryo is typically referred to as a fetus. At this stage, the fetus has developed most of its organs and body systems and is rapidly growing in size and complexity. It is also starting to exhibit more recognizable human features, such as limbs and facial characteristics.
How does the 2nd stage of the mitotic phase overlap with the 1st stage?
Prophase, or the first stage in mitosis, involves the condensing of chromatin and formation of mitotic spindles. Prometaphase, the second stage of mitosis, involves the appearance of discrete chromosomes. fragmentation of the nuclear envelope, and attachment of spindles to the chromosomes. These stages overlap in that some of these events may occur before others. For example, the nuclear envelope may desolve before the spindles fully attach to the chromosomes.
