You have a bacterial strain with a mutation that removes the transcription termination signal from the Abd operon.Which of the following statements describes the most likely effect of this mutation on Abd transcription?

A) The Abd RNA will not be produced in the mutant strain.
B) The Abd RNA from the mutant strain will be longer than normal.
C) Sigma factor will not dissociate from RNA polymerase when the Abd operon is being transcribed in the mutant strain.
D) RNA polymerase will move in a backward fashion at the Abd operon in the mutant strain.
