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 Vmax is the maximal rate at which an enzyme catalyzes a reaction. It is expressed as the amount of product formed per minute. The units of Vmax are the same as for v0. This value can be extrapolated from the plateau of the curve on the Michaelis-Menten plot.he Vmax is the maximal rate at which an enzyme catalyzes a reaction.
