Verified step by step guidance

Understand the context: The question is about DNA replication and termination processes in prokaryotes, specifically focusing on factor-dependent and rho-dependent termination.

Clarify the terms: Factor-dependent termination and rho-dependent termination are actually related to transcription termination, not DNA replication. This is a key point to identify the false statement.

Factor-dependent termination: This involves the formation of a hairpin or stem-loop structure in the mRNA, which causes the RNA polymerase to pause and eventually dissociate from the DNA template.

Rho-dependent termination: This involves the rho protein, which binds to the mRNA and moves towards the RNA polymerase, causing it to dissociate from the DNA template when it catches up.

Identify the false statement: Since both factor-dependent and rho-dependent termination are related to transcription, not DNA replication, the statement claiming they are methods for stopping DNA replication is false.
