... but not without the 5’ to 3’ exo. Therefore it must be the 5’ to 3’ exo of enzyme X that is critical in DNA replication, and cannot be replaced by action of another enzyme. The function of 5’ to 3’ exo is to degrade the primer. The other activities of enzyme X could be used for elongation and proof ...
