Explanation:
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.

The scientific method can best be described as a plan or set of procedures.
The major difference between Charles Darwin and Herbert Spencer’s theory of evolution was based on misapplying Darwin’s biological evolutionary concept by political, economical and social-based concepts.
ex
Charles Darwin was an important person in history who wrote: “On the Origin of Species”. In this work, he summed up both history and science. He explained that human evolution is based on natural selection (Organisms develop as new species by spontaneous mutations such as reproductions, having offspring, battling for foods with other organisms and avoid being killed.)
Social Darwinists used Darwin’s idea and made their own ideologies. That the biological world got developed socially and economically. Herbert Spencer, one of the Social Darwinism follower coined the term “survival of the fittest”. He expressed that the world only contains two divisions: rich and poor.
The rich were naturally fittest to survive, and the poor were weak and unfit. Also, they believed it was an error if the poor allowed to continue breeding.
