As that takes place, the original DNA shown in blue and the replicated DNA shown in green attached to different positions on the cell membrane. At the same time, the cell begins to expand and the cell begins to grow. Eventually, once we replicate our DNA, the cell basically divides into equal size daughter cells as shown in the following diagram. So budding basically involves producing two cells that are unequal in size. But binary fission involves producing two cells that contain the same exact amount of cytoplasm and therefore are the same exact in size. Now let's move on to the process of regeneration.
