MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.
The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.
A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.
The checkpoints during mitosis are:
- At the end of stage G1 and before S.
- Before anaphase in mitosis.
- DNA damage checkpoints in G1, S or G2.
The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.
That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.
Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

Spindle fibers form a protein structure that divides the genetic material in a cell. the spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both toes of nuclear division: mitosis and meiosis

The nurse recognizes the term “word salad” as describing this type of communication
Word salad is a combination of seemingly random words or phrases to form incomprehensible statements that is unclear and difficult to understand. Word salad is usually used to describe a symptom of a neurological or mental disorder (such as schizophrenia and dementia) in people. The affected persons do not usually know that they do not make sense when using word salad to communicate.
