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.
Double-stranded DNA loops around 8 histones twice, forming the nucleosome, which is the building block of chromatin packaging. DNA can be further packaged by forming coils of nucleosomes, called chromatin fibers. These fibers are condensed into chromosomes during mitosis, or the process of cell division. However, packaging of chromatin into chromosomes that we are most familiar with occurs only during a few stages of mitosis.
