Question

Mitosis unfolds through a sequence of stages marked by specific events in the cell. The structural changes in the cell are brought about by a series of tightly coordinated underlying mechanisms. Sort each process into the appropriate bin to indicate the stage of mitosis in which it occurs. If a process occurs in more than one stage, sort it to the stage when it first occurs.

Answer 1

Answer:

In single-celled organisms, cell reproduction gives rise to the next generation. In multicellular organisms, cell division occurs not just to produce a whole new organism but for growth and replacement of worn-out cells within the organisms.

Cell division is always highly regulated and follows a highly orchestrated series of steps. The term cytokinesis refers to the division of a cell in half, while mitosis and meiosis refer to two different forms of nuclear division.

Mitosis results in two nuclei that are identical to the original nucleus. Meiosis, on the other hand, results in four nuclei that each has ½ the chromosomes of the original cell. In animals, meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm.
