Are heists from gta v story mode available in online mode?

The only verified source provided is the Wikipedia entry for Grand Theft Auto Online, which describes the game as the online component of GTA V and outlines its open‑world multiplayer features. It does not mention the story‑mode heists from the single‑player campaign being carried over to the online experience. GTA Online has its own set of heist missions that are designed specifically for multiplayer play, but the evidence does not support the availability of the original story‑mode heists in online mode.
