If you take a close look at epithelial cells using a microscope, you will see them tightly packed together. This helps make a protective barrier for our bodies. There are also some special door-like connections between each epithelial cell called gap junctions. The gap junctions are where the cells exchange nutrients.
The prophase stages of both processes basically undergo the same steps. The chromatin is condensed 10,000 times into chromosomes to fit inside the nucleus of a cell, where cellular division occurs. When the chromatin becomes tightly packed, the replicated chromosomal DNA, called sister chromatids, are connected at the centromere.
