Ribosome in cell #003
And they are united by a common chain of informational ribonucleic acid. And how to check it? The electron microscope is a poor helper here — in the pictures it was possible to disassemble both individual ribosomes and assembled several pieces together. However, it was difficult to determine what connects them. But Rich and his staff weren't going to guess from the picture. They used chemistry. Wildlife has one special feature. She almost never creates anything that she herself could not destroy. For any of the most complex and resistant compounds, there is a special "master key" — an enzyme that destroys it without much energy expenditure. Dr. Rich had some ideas about a thread connecting a team of ribosomes. Therefore, he decided to test the ribonuclease enzyme, which is able to destroy only one single compound — an RNA chain. And nothing else. The experiment with labeled amino acid was repeated.
Only now, before turning on the centrifuge, a weak enzyme solution was dripped into the tube. Then, when the centrifuge was stopped and an employee with a radioactive pulse counter made the necessary measurements, the laboratory rejoiced. Although the polyribosomes had disappeared, the little thing that had refused to work in the previous experiment was radioactively labeled this time! So, the hypothesis turned out to be correct. A single ribosome does not work, it is out of play. And if several particles are joined together, they are a force. Therefore, the point is to assemble several ribosomes together and they, drawing support from each other, will begin to create protein molecules? Not at all. The enzyme didn't just break up a bunch of ribosomes. He dissolved the thread on which they were strung like beads. And this thread, as Rich's lab verified, could only be a chain of ribonucleic acid. Because the enzyme couldn't destroy anything else. So the chemist saw something that could not be seen in any microscope: how tiny machines with software control pass through themselves a tape with a task and from "pieces", "blocks" collect protein molecules. One tape per "machine" is too uneconomical, and therefore ribosomes work as a team. It was chemists, not microscopists, who calculated how many machines there are per tape, how much time it takes to assemble one protein chain. You bet! The hemoglobin chain is assembled in one minute, and they are formed on each information thread five to six times. But in bacteria, ribosomes work five times faster. At the end of the chain is a ribosome with a finished molecule. She "read&the last instructions are on the tape, I fixed the last "nuts" and slipped off the thread, pushing the finished molecule away from me. She's ready to work again, and she doesn't care what to do, what kind of molecule to build. Just like the machine doesn't care what program is put into it. So, the cage has given away its secret. Dr. Rich has done a lot. But he did not find out exactly how the ribosome itself works, how it is arranged. Is it any wonder? The large laboratory barely had enough strength to disassemble a tiny unit stacked with several ribosome machines. However, some (though not very correct) ideas about how the protein molecule is assembled already existed at that time.
