Final answer:
The holoenzyme prokaryotic RNA polymerase is a complex containing 6 proteins that bind to the yeast origin of replication and is required for chromosome replication.
Step-by-step explanation:
The holoenzyme prokaryotic RNA polymerase is a complex containing 6 proteins that bind to the A and B1 domains of the yeast origin of replication. This complex is required for replication of the chromosome.
The holoenzyme consists of alpha (a), alpha (a), beta (B), beta prime (B'), and omega (o) subunits.
