what happens during mitosis

During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.

what happens during telophase

During this phase, the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.

what happens during anaphase

Each sister chromatid of a chromosome has spindle fibers attached to it. These spindle fibers begin to shorten and pull the sister chromatids apart at the centromere. ... The chromosomes during anaphase usually have a distinct V shape.

what happens during interphase

Interphase refers to all stages of the cell cycle other than mitosis. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin

why does mitosis happen

Mitosis is a type of cell division. Mitosis occurs wherever more cells are needed. It produces two new cells that are identical to each other, and to the parent cell. The process of growth and division is called the cell cycle.

name the 4 stages of mitosis

Mitosis occurs in four phases, called prophase, metaphase, anaphase, and telophase.

why is mitosis important

Mitosis plays an important part in the life cycle of most living things, though to varying extents. In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.

what happens during prophase

Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.

what do spindle fibers do

Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.

name the 6 stages of a cell's life

The cell cycle, which includes interphase (A and 1) and mitosis, is a continuous process. Nevertheless a number of mitotic stages can be defined: prophase (B and 2), metaphase (C and 3), anaphase (mid 4 and late D and 5), telophase (E) and cytokinesis (F and 6).

what do centrioles do

The main function of the centriole is to help with cell division in animal cells. The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division (mitosis). ... Cilia and flagella help the cell move.

what is the result of mitosis

These stages are prophase, prometaphase, metaphase, anaphase, and telophase. During mitosis, the chromosomes, which have already duplicated, condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell. The result is two genetically identical daughter nuclei.

what are chromosomes

a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

what are chromatids

each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA. (half of what a chromosome is, strands of bunched up DNA)

what happens during metaphase

the chromosomes, guided by the spindle fibers, line up in the middle of the dividing cell.
