What is the simple definition of telophase?
Definition of telophase
1 : the final stage of mitosis and of the second division of meiosis in which the spindle disappears and the nucleus reforms around each set of chromosomes.
What is telophase in a sentence?
the final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle 2. the final stage of mitosis. 1. Telophase then brings meiosis I to a close: the nuclear envelope starts to form again.
What is an example of telophase?
Telophase marks the end of mitosis. By this time, a copy of each chromosome has migrated to each pole. These chromosomes are surrounded by a nuclear membrane that forms at each pole of the cell while the cell is pinched in the middle (for animals) or divided by a cell plate (for plants).
What is the best description of telophase?
noun Biology. the final stage of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes.
What is telophase Class 11?
Telophase is the fourth and last step of M-phase in which following events takes place : 1. Chromosomes present in the cell start to uncoil and lead to the formation of chromatin. 2. Nuclear envelope re-formed.
What is a simple definition of cytokinesis?
cytokinesis, in biology, the process by which one cell physically divides into two cells. Cytokinesis represents the major reproductive procedure of unicellular organisms, and it occurs in the process of embryonic development and tissue growth and repair of higher plants and animals.
What is telophase II?
Telophase II is the stage in meiosis II that follows after anaphase II. In anaphase II, the sister chromatids that were formerly joined at the centromere are separated from each other and moved away to opposite poles. … The complete movement and separation of sister chromosomes mark the telophase II.
What happened telophase 1?
During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
What is another term for telophase?
process. miosis, reduction division, mitosis, meiosis.
What is cytokinesis in animal cells?
Cytokinesis is the last step of cell division that partitions the cellular organelles and cytoplasm of one cell into two. In animal cells, cytokinesis requires Rho-GTPase-dependent assembly of F-actin and myosin II (actomyosin) to form an equatorial contractile ring (CR) that bisects the cell.
What is cytokinesis in zoology?
Cytokinesis is the process by which a cell divides its cytoplasm to produce two daughter cells. The separation of one cell into two is accomplished by a structure called the contractile ring. …
What is the definition of prophase 2?
Prophase II is the phase that follows after meiosis I, or after interkinesis if present. If interkinesis takes place, the nuclear envelope and the nucleolus disintegrate during prophase II. The chromosomes are condensed. The centrosomes replicate and move towards the opposite poles.
What happens cytokinesis?
Cytokinesis is the physical process that finally splits the parent cell into two identical daughter cells. During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.
Why is the telophase important?
Telophase is the final stage in cell division. During telophase, the nuclear envelopes reform around the new nuclei in each half of the dividing cell. … In order to allow the new cells to begin producing the necessary proteins and to protect the DNA, a nucleus must reform in each cell.
