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.

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?
Yes, I agree with both of them, 1 U or IU is defined as the enzyme quantity that liberates 1 microgram or micromole of product per ml of the reaction mixture per minute. ... Â·. For IU and kat, the units are predeined. If you want to use others units (mol, mmol, Âµmol,... or g, mg ... per seg, min or h, etc.), write U and give the definition. The enzymatic activity unit is defined by the IUBMB (International Union of Biochemistry and Molecular Biology) in 1981.
