WebMost prokaryotes contain a single circular chromosomal DNA molecule that is highly compacted inside the cell. In fact, if you were to stretch out the chromosome in a bacterium, it would be about 1.4 millimetres long, compared to the bacterium itself that can vary from 0.2 to 2.0 micrometres long! WebChromosomes undergo four major transactions: replication, segregation, condensation and decondensation (Hirano, 2000) (Fig. 1D–F). These transactions are performed in every cell, in a fixed order one after another, forming their own cycle within the cell cycle.
