Principle of Dominance When Mendel crossed the pollen from a purple flower onto a white flower, he found that all of the seeds produced offspring with purple flowers. He concluded that some traits were dominant over other (recessive) traits. He determined that dominant traits appear more often. When Mendel crossed the pollen from a plant with green pods with a plant with yellow seed pods, all of the offspring had green seed pods. This told him that (Type here) seed pods were dominant over (Type here). seed pods.

C3 transferase decreases Rho activity and contractility by decreasing the number of stress fibers and thus also reducing wrinkles

Explanation:

Rho protein is a small GTPase, i.e., an enzyme that binds GTP to hydrolyze it to GDP, which is known to mediate the formation of stress fibers and focal adhesion. Rho protein is involved in diverse cellular functions including, among others, adhesion, motility, and division by reorganization of the actin cytoskeleton. The bacterial toxin C3 transferase derived from Clostridium botulinum is able to lock Rho in an inactive state. C3 transferase adds an ADP-ribose to Rho, thereby leading to the accumulation of a Rho-guanine nucleotide dissociation inhibitor (GDI) complex in the cytoplasm. In consequence, C3 transferase functions to decrease contractility by blocking Rho activity, decreasing the number of stress fibers and leading to a reduction in wrinkles.
