Diploid nuclei of the ascomycete Neurospora crassa contain 14 chromosomes. A single diploid cell in an ascus will undergo one round of meiosis, followed in each of the daughter cells by one round of mitosis, producing a total of eight ascospores. G2 occurs after DNA synthesis, so the diploid G2 nucleus has 2n chromosomes, yet "4n" genetic material since chromosomes are counted by virtue of the number of centromeres present. The mature ascospore will be haploid in chromosome count ergo, 7 chromosomes , and will have "n" genetic material ergo, ng.

A Newfound Source of Cellular Order in the Chemistry of Life | WIRED

Imagine packing all the people in the world into the Great Salt Lake in Utah—all of us jammed shoulder to shoulder, yet also charging past one another at insanely high speeds. That gives you some idea of how densely crowded the 5 billion proteins in a typical cell are, said Anthony Hyman, a British cell biologist and a director of the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden. Somehow in that bustling cytoplasm, enzymes need to find their substrates, and signaling molecules need to find their receptors, so the cell can carry out the work of growing, dividing and surviving. If cells were sloshing bags of evenly mixed cytoplasm, that would be difficult to achieve. But they are not. Membrane-bounded organelles help to organize some of the contents, usefully compartmentalizing sets of materials and providing surfaces that enable important processes, such as the production of ATP, the biochemical fuel of cells. But, as scientists are still only beginning to appreciate, they are only one source of order.
