Your question: What could be the consequences of such a mitotic error?

Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.

What is a mitotic error?

Mitotic errors leading to chromosome missegregation are a hallmark of human cancers. These errors result from incorrect microtubule attachments to specialized regions on chromosomes called kinetochores.

What disease is associated with mitosis?

Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.

Who does Turner syndrome affect?

Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.

Does polyploidy occur in humans?

Polyploid cells are found in diverse taxa (Fox and Duronio, 2013; Edgar et al., 2014), and in fact entire organisms can be polyploid, or polyploid cells can exist in otherwise diploid organisms (endopolyploidy). In humans, polyploid cells are found in critical tissues, such as liver and placenta.

What are the 3 phases of oogenesis?

Oogenesis involves three key phases: proliferation, growth, and maturation, during which PGCs progress to primary oocytes, secondary oocytes, and then to mature ootids [1].

What if conditions Cannot be repaired?

If a cell has an error in its DNA that cannot be repaired, it may undergo self-destruction (apoptosis ). Apoptosis is a common process throughout life that helps the body get rid of cells that no longer work or that it doesn’t need.

What are two reasons mitosis is important for organisms?

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
