Sometimes a caulobacter attaches the end of its stalk to the body wall of a bacterium of another species and feeds by sucking out the victim's protoplasm...
Lois Hook asks: "Whatever will the churches say when the biochemists successfully synthesize protoplasm?" Answer: simply that God has at last let them in on one of his own formulas...

...nuclei of reproductive cells are mere blobs of protoplasm, apparently much alike. But each of them contains a genetic "instruction code" that tells it how to develop into a particular sort of creature, ranging from a bacterium to a man. In the case of higher animals, the cell's instructions are carried by long, coiled-up molecules of DXA (deoxyribonucleic acid). In the instance of some viruses, which are the simplest of organisms, the code is found in RNA (ribonucleic acid), which is less complicated...
Skilled Cell. The idea was not original with Beadle. Every biologist marvels at the chemical virtuosity of living cells. Under the eye of the microscope they seem placid things. The slimy protoplasm inside them sometimes streams slowly, but little other action is visible. This quietude is an illusion. The typical cell, which may be only one twenty-five-thousandth of an inch long, is aboil with chemical action. It is building thousands of complex compounds and tearing other thousands to bits. It selects nutrients that it wants, and in some mysterious way absorbs them selectively through its outer wall. Tiny...
