Cell structure is the , which controls replication of chromosomes prior to cell division.

The answer is "Nucleus" and "Center"

Explanation:

Organisms comprise of a large number of cells, however like every other living being, you begun life as a solitary cell. How could you create from a solitary cell into a living being with trillions of cells? The appropriate response is cell division. After cells develop to their greatest size, they partition into two new cells. These new cells are little from the outset, yet they develop rapidly and at last separation and produce all the more new cells. This cycle continues rehashing in a ceaseless cycle.

Cell division is the cycle wherein one cell, called the parent cell, partitions to frame two new cells, alluded to as girl cells. How this happens relies upon whether the cell is prokaryotic or eukaryotic.

Cell division is easier in prokaryotes than eukaryotes on the grounds that prokaryotic cells themselves are less complex. Prokaryotic cells have a solitary roundabout chromosome, no core, and few different organelles. Eukaryotic cells, interestingly, have various chromosomes contained inside a core and numerous different organelles. These cell parts must be copied and afterward isolated when the cell separates.
