Just like your day has a routine from day to night, cells have routines of their own. The cell cycle is generally described as consisting of four main phases: G1, S phase, G2 and mitosis (or meiosis).

Sister chromatids then segregate to opposite poles during meiosis II, which results in the formation of nonidentical haploid gametes. Note that the lengths of the cell-cycle stages are not drawn ...

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.

During the meiotic cell cycle, DNA replication is followed by two rounds of chromosome segregation, in which homologues segregate during the first division and sister chromatids are partitioned in ...
