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 perirhinal cortex is particularly important in visual recognition and receives more input from the occipital lobe than from other cortical areas. In addition, the perirhinal cortex is a cortical region in the medial temporal lobe that is made up of Brodmann areas 35 and 36. It obtains highly administered sensory information from all sensory regions and is usually accepted to be a significant region for memory.
Hey there mate!
I know that the farther you go back, the more that the ancestors would most likely have no resemblance and it would even look like they don't look like each other. There would be basically (unrelated) from one another.
So, based from your options listed above, I believe that the correct answer to this question would be (<span>animals descended from one ancestor)</span><span>.
I hope this would help you!</span>
