Transcription termination in prokaryotes often involves specific factors. The ρ (rho) factor is a protein that binds to the RNA and moves along it until it catches up with the RNA polymerase, causing the enzyme to dissociate from the DNA and thus terminating transcription. Other factors like α (alpha), γ (gamma), and σ (sigma) have different roles in transcription initiation or enzyme structure, not termination.
Hence, the correct answer is option (4).
