1) Binary fission in prokaryotes is the process by which the circular DNA of the cell is replicated and then turned into 2 daughter cells. After the replication of the double stranded begins at the origin of replication, the strands are fully copied and then partitioned in the cell. The site of separation starts in the beginning of the cell with the molecule FtsZ. The physical separator is called the septum, which grows until finally the cell pinches off into two. 2) Interphase, the term used for everything but mitosis, consists of the G1, S, and G2 phases in that order. During the G1 and G2 phases, proteins and organelles are manufactured for the new cell. During the S phase, chromosomes replicated into sister chromatids that are attached by kinetochore microtubules at the centromere. This construction makes it easier to replicate the DNA. The G2 phase also has these chromosomes begin to coil during a condensation reaction and also forms centrioles which eventually draw the chromosomes apart. 3) Cytokinesis in animals occurs when actin filaments pull the sides of the cell to create a
