They carry a code indicating destination:

"In 1971, Dr. Blobel and a colleague, Dr. David D. Sabatini, who later headed cell biology studies at the New York University School of Medicine, proposed a bold idea known as the “signal hypothesis.” It suggested that each protein carries in its structure a sequence of signals comparable to address tags on airport luggage or ZIP codes on mail to ensure that it all arrives safely.

"The signals, Dr. Blobel found, are chains of amino acids created by protein-making machines that read distinctive RNA codes and then fix them on each new batch.

"Like transmitters, these signals order receptors in membranes to open up watery holes so that proteins can pass through. They then act as GPS devices to cross the crowded terrain of a cell or a human body and, like finding a mailbox across the universe, penetrate precisely the right worksite organelle for each protein’s assigned task.

"Despite proteins’ variety and complexity, however, Dr. Blobel demonstrated that their signaling system for getting through barriers and finding their worksites is universal, operating similarly in all animals, plants and even common yeasts.

"Moreover, he found, this signaling system has evidently been working quite smoothly for millions of years, since the evolution of the first cell. Mistakes can be catastrophic to an organism, but they are relatively rare.

“'Günter Blobel’s discovery has had an immense impact on modern cell biological research,” the Nobel Assembly at the Karolinska Institute in Stockholm said in announcing the prize on Oct. 11, 1999. “Furthermore, knowledge about the topogenic signals has increased our understanding of many medically important mechanisms.'”

Comment: There is no way this highly complex and purposeful living address system for cell protein products could have developed except by design by God.
