A. Cell junctions in areas are subjected to great mechanical stress, such as the skin and heart muscles
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.

<span>I don't know if you have any options, but I'd say that the rhyme scheme of this poem is aabbcc, etc. - this means that two lines rhyme, and then the next to lines rhyme, etc. The entire poem is written in the octosyllabic couplet, meaning that each line has 8 syllables (an octave), and the term couplet refers to the rhyme - that every two lines rhyme. </span>
