The nucleus is found in every cell of the living organism except in a few such as in prokaryotic cells. It is referred to as the director of the cell. It performs various functions at the molecular level. The membrane that covers the nucleus is called the nuclear membrane....
What are the major similarities and differences between eukaryotic and prokaryotic cells? What information is contained within the nucleus and what role does it play in the cell? What are the main structures within the cell nucleus? What organelles can be found in both a single-celled eu...
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
Under physiological conditions, mRNA, with the exception of a few mitochondrial transcripts, is produced in the nucleus, transported to the cytosol, and translated by ribosomes into a protein. The mRNA is then quickly metabolized. mRNA in the cytoplasm has a short half-life due to the ...
The DNA, the molecule that holds the secret code to making proteins, is contained within the nucleus. Normally, DNA is contained within a complex consisting of the DNA wrapped up in proteins called chromatin. The blueprint for making all proteins is contained within the DNA molecule....
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
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 ...
A lesion that presents on one side of this type of nucleus has the potential to cause muscle paralysis and atrophy in the areas surrounding the lesion. When the palate becomes paralyzed, speech is almost certain to be affected. This is a result of air escaping into the nose when the patien...
In cell biology, the cytoplasm is all of the material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. Hyaloplasm The clear fluid portion of cytoplasm as dis...
In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom. The electrons are distributed around the nucleus and occupy most of the volume of the atom. What is matter according to Empedocles?
