A scientist uses recombinant technology to take a eukaryotic promoter and place it in front of a bacterial structural gene.What is the most likely outcome on bacterial gene expression?
A)Bacterial gene expression will increase because both prokaryotic and eukaryotic genes are based on the same four nucleotides.
B)Bacterial gene expression will not occur because RNA polymerase enzymes between prokaryotes and eukaryotes are incompatible.
C)Bacterial gene expression will increase because eukaryotic RNA polymerase has analogous function to prokaryotic RNA polymerase.
D)Bacterial gene expression will decrease slightly because prokaryotic RNA polymerase cannot transcribe eukaryotic genes as efficiently as prokaryotic genes.

Bacterial gene expression will not occur because the RNA polymerase enzymes between prokaryotes and eukaryotes are incompatible. Eukaryotic promoters are not recognized by bacterial RNA polymerase, which is necessary for initiating transcription.
