I stand corrected on that point. Enzymes have generally been classed as proteins, but the ribozyme would be an exception to that. And yes, I do understand that the whole point of the RNA world hypothesis is that RNA can in some cases have some catalytic ability.
But it’s my understanding that peptidyl transferase is essentially a stretch of RNA within the ribosome. Is that correct? And RNA is considered a macromolecule. So it’s not wrong to call it a molecule, and that’s what I was originally defending – my use of the term “molecule.” Of course, if you want to go pedantic again, and say that within the ribosome it’s not called a “molecule” but a “moiety”, well, have it your way.
I didn’t say that it was. I understand it to be an organelle, composed of more than one kind of molecule.
I read that column, long ago. Give me the link to it again. The author did admit that Meyer made a slip, but did the author agree that the slip invalidated Meyer’s entire book? Or even the entire chapter? I have my doubts. But give me the link, and I’ll review it.
