Cell nucleus
The nucleus is the largest cellular organelle in animal cells.
In mammalian cells, the average diameter of the nucleus is approximately 6 micrometres (µm), which occupies about 10% of the total cell volume. The viscous liquid within it is called nucleoplasm (or karyolymph), and is similar in composition to the cytosol found outside the nucleus. It appears as a dense, roughly spherical or irregular organelle. The composition by dry weight of the nucleus is approximately: DNA 9%, RNA 1%, Histone Protein 11%, Residual Protein 14%, Acidic Proteins 65%.
Nucleus (video game)
"Nucleus" is a puzzle-based shooting game with a dual stick control system similar to . Players are tasked with ridding a host body of a virus infestation, moving through the body's three main biological systems, the digestive system, the circulatory system, and finally the nervous system, culminating in a final battle in the brain.
