WebCells need to copy their DNA very quickly, and with very few errors (or risk problems such as cancer). To do so, they use a variety of enzymes and proteins, which work together to make sure DNA replication is performed smoothly and accurately. DNA polymerase One of the … 3) Eukaryotic DNA is generally much longer, more complex (typically multiple linear … WebEukaryotic cells reproduce genetically identical copies of themselves by cycles of cell growth and division, instead of by binary fission. The cell cycle diagram shows that a cell division cycle consists of 4 stages: G1 is the period after cell division, and before the start of DNA replication.
