“Cellular activity” is a rather vague term, however, and considering that a nucleus is the “brain” of a cell, that activity deserves some explication. Similar to human beings and their brains, without a nucleus, a cell would be unable to function and would immediately perish. That being...
The nucleus is perhaps the most important structure inside animal and plant cells. It isthe main control center for the cell and acts kind of like the cell's brain. ... In fact, the definition of a eukaryotic cell is that it contains a nucleus while a prokaryotic cell is defined as no...
What is a nucleus in a cell?Parts of the Cell:The cell is the basic unit that makes up all living things, and all multicellular organisms are made of eukaryotic cells. Eukaryotic cells have a nucleus, as well as many different membrane-bound organelles inside....
What makes DNA an acid? Acidity of DNA Deoyriribonucleic acid is located primarily in the nucleus of eukaryotic cells, although the mitochondria has its own specific DNA. The name of the structure comes from the fact that under normal conditions it is acidic and contained in the nuclear region...
The nucleus directs all activities that occur within the cell and also contains the cell’s genetic material, or DNA.The nucleus gives the signal to the cell to grow, divide or make proteins. A nuclear envelope surrounds the nucleus, allowing only certain substances to enter and exit. ...
When Z protons and N neutrons combine to form a nucleus, mass equal to mass defect disappears and the corresponding energy is released. This is called the binding energy of the nucleus (BE) and is equal to (Delta m)c^(2). BE = (Zm(p) + Nm(n) -M ) c^(2

discovered it was easier to create a nucleus and then build up an OS, instead of converting existing OSes to be compatible with new hardware. This nucleus -- or kernel -- contained all source code to facilitate communications and support systems, eliminating the need to directly program on ...
light). Such 'ballistic' protons have led to many interesting discoveries in particle physics / chemistry. One reason why protons are so important for such research is that, unlike neutrons, protons are stableoutside of an atomic nucleus, which makes it possible to use them in certain ...
