Solution
The sequence that does NOT contribute to the proper expression of a eukaryotic protein-coding gene is the "Consensus -10 and -35 sequences that directly bind RNA polymerase."
This is because these sequences are specific to prokaryotic genes, not eukaryotic. In prokaryotes, the -10 and -35 sequences in the promoter region of the gene are recognized by the RNA polymerase to initiate transcription.
In contrast, eukaryotic genes have a more complex system of transcription regulation involving core promoter elements like the TATA box, binding sites for transcription activator proteins, signals for RNA cleavage
