What is anaphase and example?
Definition. The third stage in the first meiotic division after prophase I, and highlights the separation of paired homologous chromosomes towards opposite ends of the cell. Supplement. Meiosis is a specialized form of cell division that ultimately gives rise to non-identical sex cells.
What is anaphase simple terms?
Definition of anaphase : the stage of mitosis and meiosis in which the chromosomes move toward the poles of the spindle.
What occurs in anaphase quizlet?
What happens during Anaphase? The spindle fibers SPLIT APART the sister chromatids and move them to opposite ends of the cell, equally dividing the genetic material.
What is anaphase and telophase?
As the third phase—anaphase—begins, the chromatids separate and move to opposite ends of the cell. Once the chromatids separate, they are called chromosomes. In this way a complete set of chromosomes migrates toward each centriole. In the last phase—telophase—the cell divides.
What happens in metaphase I?
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell.
What is telophase mitosis?
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
What is Interkinesis in meiosis?
Interkinesis or interphase II is a period of rest that cells of some species enter during meiosis between meiosis I and meiosis II. No DNA replication occurs during interkinesis; however, replication does occur during the interphase I stage of meiosis (See meiosis I).
What is telophase short?
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 cytokinesis easy?
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.
How common are laggards in aberrant anaphases?
Most of the aberrant anaphases contained laggards, which agrees with the results of the parallel series without Cyt-B ( Catalán et al ., 2000) and with previous studies ( Lindholm et al ., 1991; Ford and Correll, 1992 ). Laggards were found in 95.2 and 93.5% of aberrant bipolar and multipolar anaphases, respectively.
Do Bipolar anaphases show autosome laggards in lymphocytes?
Subsequently, most `extra’ MN seen in multinucleate cells contain autosomes. In lymphocyte cultures treated with Cyt-B, bipolar anaphases appear to show more autosome laggards but fewer lagging fragments and X chromosomes than without Cyt-B.
What is a good sentence for laggard?
EXAMPLES – Laggard in a Sentence The point of reference for the laggard is the past. (source) Tories deny Canada a ‘laggard’ at anti-bribery measures (source) Kentucky and Indiana also fell into the “laggard” category. (source) “laggard” when it came to proper investment in human capacity. (source)
Why are XFX laggards more efficiently micronucleated in cyt-b-treated cells?
X laggards are particularly efficiently micronucleated in Cyt-B-treated cells, perhaps because they stay further away from the poles in round cytokinesis-blocked anaphases than in normally elongated non-blocked anaphases.
