To repair cells in our body.
What is Mr. Lyons version of IPMATC?
Irving Pass Me A Taco Chief.
What type of cells are involved with Meiosis?
Haploid and Diploid.
In what phase of mitosis does spindle fibers first form?
What is the end result of IPMATC?

What happens during Meiosis prophase II.
A second set of phases begins as the spindle apparatus forms and the chromosomes condense.
(2000 Point SPECIAL) In a certain species of plant, a rare genetic mutation occurs that leads to the formation of an extra centrosome during mitosis. Describe the potential consequences and challenges that may arise as a result of this mutation, specifically in terms of the accuracy and integrity of chromosome segregation during cell division. Additionally, discuss potential cellular and organismal implications that may arise due to this abnormality in mitotic processes.
The presence of an extra centrosome during mitosis can have several consequences and challenges related to chromosome segregation and overall cellular and organismal implications. Here are some potential outcomes:
Abnormal spindle formation: The centrosomes play a crucial role in spindle formation, which is responsible for segregating chromosomes during mitosis. The presence of an extra centrosome can lead to the formation of multipolar spindles instead of the normal bipolar spindle. This can cause errors in chromosome segregation, resulting in unequal distribution of genetic material to daughter cells.
Chromosome missegregation: The formation of multipolar spindles due to the extra centrosome can lead to errors such as merotelic attachments, where a single chromosome becomes attached to microtubules from multiple spindle poles. This can result in lagging chromosomes or chromosomal breakage, leading to aneuploidy (abnormal chromosome number) in daughter cells.
Cytokinesis defects: The presence of multiple spindle poles can disrupt the formation and positioning of the contractile ring during cytokinesis, the final stage of cell division. This can lead to cytokinesis failure or unequal distribution of cytoplasmic components, resulting in the formation of multinucleated cells or cells with unequal sizes.
Cellular and organismal consequences: The abnormality in mitotic processes caused by the extra centrosome can have severe implications for the affected cells and the organism as a whole. It can lead to genomic instability, as cells with aneuploidy or chromosomal rearrangements are prone to further mutations. Additionally, the presence of abnormal cells can disrupt tissue architecture and function, potentially leading to developmental abnormalities, impaired organ function, or even increased susceptibility to diseases such as cancer.
Overall, the presence of an extra centrosome during mitosis can significantly disrupt the accuracy and integrity of chromosome segregation, potentially resulting in a wide range of cellular and organismal consequences.
-The spindles break down
-Chromosomes uncoil and form two temporary nuclei
-The cell divides.
