A cell undergoing cell division identifies a chromosomal misalignment. How does this normally affect the progress of the cell cy
telo118 [61]

When a cell undergoing cellular division identifies that a chromosome misalignment had taken place the cell cycle stops until the error it's corrected.

Option two of the question states that the cell cycle will <u>proceed uncontrollably, this is not the case for the error at hand</u>. Although this can be a problem for cells and leads to the appearance of cancer, it is not caused by chromosome misalignment. As is the case with options 3 and 4.

The stop or delay in the <u>cell cycle is what normally takes place in these situations.</u> This stoppage is done by the <em><u>spindle checkpoint</u></em>, which prevents <u>duplicate chromosomes from separating.</u>

During this time, the error it's corrected. If a cell is not able to correct the error at this time, many situations can follow. <u>However, the most likely is that the cell will undergo a <em>programmed cellular death.</em> </u>
