The September 2012 rainfall total at Adelaide (Kent Town) was 21.8mm received on 12 rain days. This is very much below the long term average of 60.3 mm on 13 or more rain days, and results in the driest September in Adelaide since 2008 when only 16.0 mm was observed.
Chromatin condenses to form chromosomes during  prophase of mitosis, and during prophase I and prophase II of meiosis. Chromatin is a dense, complex fibrous structure composed of associated proteins and molecules of deoxyribonucleic acid, or DNA, which contains the genetic material of an organism.
Figure 1: During prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures.
