In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).

Cell division is the process in which a parent cell divides, giving rise to two or more daughter cells. It is an essential biological process in many organisms. During many cell divisions, however, proteins, membrane compartments, organelles, or even DNA are asymmetrically distributed between the two daughter cells. wordpress. Replication of the DNA must occur. Although persistence of adherens junctions is needed for epithelial integrity, these junctions are continually remodelled during cell division. com.

Of course, that's lightening speed During development and throughout adult life, epithelia are continuously growing or regenerating, largely as a result of cell division. (Of course rare "mistakes" occur -- cells actually have evolved to favor rare mistakes. Reply 1 2. The time-lapse was recorded in a lab over a 33-hour period. Cell division usually occurs as part of a larger cell cycle. It starts when the DNA in the cell's nucleus, usually a scramble of stretched-out spaghetti, duplicates itself, then coils into tightly packed structures shaped more like stubby macaroni. Show less
