An ignition coil is essentially a step-up transformer.
So the low voltage/high current primary side won't have much resistance since it has fewer windings than the low current/high voltage secondary side.

Misfires can come for internal coil windings breakdown (usually when the coil gets warmed up), broken conductor in the plug wire, broken insulation of the plug wire causing shorts to chassis ground, loose fitting plug cap, etc.
If both cylinders are affected, it could possible be a failing pulse generator sensor, or the ignition converter (CDI box).
