cell cycle . The first stages of the cell cycle involve cell growth, then synthesis of DNA . The single strand of DNA that makes up each chromosome produces an exact copy of itself.

With very few exceptions, mitosis occupies a much smaller fraction of the cell cycle than interphase. The difference in DNA compaction between interphase and mitosis is dramatic.

In eukaryotes, the cell cycle consists of four discrete phases: G 1, S, G 2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually ...

How Cells Divide: Mitosis vs. Meiosis by Rick Groleau As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced.

Study cell division including DNA, chromosomes, mitosis and the cell cycle, cancer and carcinogens, cell differentiation and stem cells.
