Each time the message of the gene is transcribed into a protein, another ubiquitin molecule is chained on. Five ubiquitins in the chain and the protein is automatically destroyed.

By contrast, VA induces a small-scale vibration in the tissue, and it is this low-frequency signal that provides the crucial information about tissue stiffness.

... people. The electrons are able to get off at the spot that they need to because the protein motion adjusts the energetics until it is just right. Even if the elevator starts a little too high or low (initial energies are not optimal), the people (electrons) can still get off on the right floor.

That leaves lamin A stuck to its guide molecule, which in turn is stuck in the nuclear membrane. Scientists believe this misplacement ...ACS News Service Weekly PressPac -- March 21, 2007
