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 is the purpose of the cell nucleus concerning genetics and evolution? Nuclei: Nuclei (plural for nucleus) are found in eukaryotic species, but not in prokaryotes. In fact, the name "prokaryote" is derived from Greek words that mean "before the nut." In this case,nutrefe...
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...
They break down the cellular components needed for survival, and they spur production of enzymes known as DNases, which destroy the DNA in the nucleus of the cell. It's like roadies breaking down the stage in an arena after a major band has been through town. The cell shrinks and ...
A proton is a subatomic particle found in the nucleus of atoms that differs from the other subatomic particles (called neutrons) in the nucleus of most atoms because each proton has a positive charge of +1 (as opposed to neutrons, which have no charge).
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.
