Quick question about cell division

[scilearner]

Hello everyone,

 

When a cell divide, do the organalles divide, or does DNA divide first, and using that DNA information new cells synthesize organalles. Thanks

In the early stages the cell grows and stores up energy and building materials plus it begins to build some key structures used in the process then the DNA is duplicated then spits/separates during mitosis and then immediately following that during cytokinesis the nuclei and the balance of the organelles and membranes are duplicated and then the cell divides.

Thanks I oversaw the cell growing bit. Now it makes sense. Thanks

I think it would be easier if you took the interphase. The interphase has three characteristic steps: G1, S and G3.

 

The G1 concerns the cellular growth, and happens right after the cellular division and the formation of the cell.

 

S stands for the replication of the DNA molecule. This molecule should be correctly copied, to avoid mutations.

 

G2 is related with the duplication of other organelles. This duplication will prepare the cell to divide itself.

 

So as you can see, either DNA molecule and organelles are divided; however, although the DNA molecule is correctly (under ideal conditions, of course) duplicated, the other organelles are not. This means that during cytokinesis it's not important to made an equal division of the organelles, because the two resultant cells are able to create those new organelles, because of the information of the DNA strand they receive.
