Genomic imprinting: The phenomenon of parent-of-origin gene expression. The expression of a gene depends upon the parent who passed on the gene.For instance, two different disorders-Prader-Willi syndrome and Angelman syndrome -- are due to deletion of the same part of chromosome 15.enomic imprinting: The phenomenon of parent-of-origin gene expression. The expression of a gene depends upon the parent who passed on the gene.
Todayâs lesson is brought to you by 7, 14, and the letters. Kw, pH. Kw: the ion-product constant of water Q: will pure distilled water conduct electricity A: As the demo shows, it will (slightly). If water conducts electricity, ions must exist Water exists as an equilibrium, which is referred to as the self-ionization of water: H2O + H2O ï« H3O+(aq) + OHâ(aq) Kw What is the value of Kw?
The shape of the equilibrium curve depends upon the reaction mechanism and can be. used to decide between different equilibrium models. Equilibrium constants. An equilibrium constant, designated by a upper case K, is the ratio of the equilibrium. concentrations of reaction products to reactants or vice versa. For the bimolecular reaction, A+B ïï AB, we can define an equilibrium dissociation. constant (Kd) or an equilibrium association constant (Ka), which are reciprocally.
