Answer:
because of their size but their cellular type and metabolism, known as Eukaryotic, is the same as that of much larger multi-cellular organisms.
Explanation:
So the marine animals don't eat the plastics that could be recycled and used for other products other than killing marine creatures.
Answer:
it is a stage in life
Explanation:
because it shows how one has progressed or developed
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.
