Define the term binding energy. Atomic Nucleus: The residents i.e. protons and neutrons of the nucleus are called the nucleons. In nuclear chemistry, we often study how the residents may change in nuclear reactions and by physical processes such as bombardment. In general, however, especially ...
Define or describe the following term: Organelle Cytoplasm: A typical eukaryotic cell has three major components that define its structure. These are the cell membrane, cytoplasm, and nucleus. The cytoplasm comprises a semifluid, colloidal ground substance known as the cytosol. The cytosol contains ...
Decay constant of a radioactive element is the reciprocal of the time during which the number of atoms left in the sample reduces to 1//e times the original number of atoms in the sample.
When the cell is threatened by elevated oxidative stress, however, Keap1 undergoes modification and loses its ability to ubiquitinate Nrf2, allowing it to accumulate in the nucleus to induce the expression of its target genes31. Moreover, Keap1 was found to be able to bind Nestin, which is ...

YAP, a transcriptional co-activator, is a mechanosensitive transducer of extracellular cues that is actively translocated to the nucleus during collective invasion in invasive cancer models [17]. During this process, mechanical cues through integrin mediated ECM adhesion promote YAP activity, driving ...
Drug abuse leads to mesolimbic and mesocortical neuroadaptations, which may underlie core aspects of addiction such as long-term heightened craving during withdrawal and high rates of relapse [1]. The mechanisms responsible for these persistent neuroadaptations are still unknown. Epigenetic mechanisms ...

atoms are the basic unit of particles. An atom contains a nucleus (consisting protons and neutrons) and some electrons moving around the nucleus. If o atoms have the same number of protons they are the same element. There are about 117 elements have been found or synthesized. ...
