Final answer:
The E. coli DNA polymerase III monomeric unit consists of α, ε, θ, and τ proteins and has specific roles for replication and stability.
Step-by-step explanation:
The E. coli DNA polymerase III monomeric unit consists of four proteins: α, ε, θ, and τ.
The α subunit is responsible for assembling the polymerase on the DNA.
The ε subunit aids in proofreading the DNA sequence during replication.
The θ and τ subunits have structural roles and help stabilize the DNA polymerase III complex.
