The origin of cell structures might be hypothesized to have involved a hypercycle, based on mutualism at the molecular level. Which of the following is correct regarding the hypercycle model?
1) The hypercycle model suggests that early cells formed through a process of mutualistic interactions at the molecular level.
2) The hypercycle model proposes that cell structures originated from a single ancestral cell.
3) The hypercycle model explains the evolution of cell structures through a series of self-replicating RNA molecules.
4) The hypercycle model is based on the theory of endosymbiosis.
