How 5S rRNA Gets Into the Ribosome

For a minor component, it gets a lot of molecular love. As mentioned several times in this space, the ribosome, which synthesizes proteins according to mRNA instructions, is an extremely ancient and complicated machine. Its core, including the catalytic site, is RNA. This marks it as a hold-over from the RNA world, as the thing that made proteins, (probably tiny proteins at first), before proteins…
