“The substitution of tryptophan residues, therefore, does not affect actin self-assembly into filaments.”

“The regulation of contractility in striated muscle by calcium is effected via tropomyosin on the actin filament.”

“It kinks, detaches itself from actin, unkinks, and reattaches, and thereby ratchets along the actin filament in a series of power strokes.”

“The germination of seeds in the spring is dependent upon the variations in the amount of actinism or chemical influence of light and heat.”

“In the autumn, when the ripening period arrives, light and actinism give way to a greater ratio of heat.”

“In summer, when the maturing process advances, light and heat increase, and actinism relatively declines.”

“This view, which by a mass of evidence may be shown to be erroneous, is exerting a very prejudicial effect on the progress of actinochemistry.”
