Suppose that the string of A nucleotides following the inverted repeat in a rho-independent terminator was deleted but that the

inverted repeat was left intact. How will this deletion affect termination? What will happen when RNA polymerase reached this region?

Answer: is seen below

Explanation:

Termination will not take place if the strings of A nucleotides following an inverted repeat of rho- independent termination ( which forms an hairpin structure)were deleted. Although, RNA polymerase may pause briefly at the hairpin, the presence of A- U base pairs is needed to destabilize the DNA - RNA interaction and to end transcription. If the string A nucleotides is not present, then transcription of RNA polymerase will continue.
