I know that, in the RNA world, it has been suggested that the first protocell formed by a hollow liposome structure encapsulating an RNA molecule. However, from then on it becomes confusing: I've heard that a liposome can divide when there is some force applied on one of its sides; however, if RNA replication results in such force being applied, why doesn't protein synthesis?

I've been trying to come up with potential reasons why this would happen, and I've made some research, but so far, all in vain. Any answer explaining how RNA replication - and not tRNA translation - is both sufficient and necessary for cell division would be appreciated.
