Name the fundamental properties of DNA 3. It thus makes sense that this is not only the sum of its constituent energies, since we expect that some other energy is spent to keep the nucleus together. Definition of isotope. nucleus (LDT) and the adjacent pedunculopontine tegmental nucleus (PPT). Template #07913 LMNA gene produces the Lamin A protein, which is the structural scaffolding that holds the nucleus of a cell together. • Binding energy per nucleon generally decreases from atoms with a mass number around 56 to larger atoms. Introductory Nuclear Physics – 1; The Liquid Drop Model Each nucleus is a bound collection of N neutrons and Z protons. It is normally one of the excited states of the nucleus formed by the combination of the incident particle and target nucleus. The Nucleus A simple description of the nucleus tells us that it is composed of protons and neutrons. To determine the spin of a given nucleus one can use the following rules: If the number of neutrons and the number of protons are both even, the nucleus has no spin. mA, 0.
