When lactose is absent, ______________________ __________________ can bind to the promoter and transcription can occur in the lac operon. 9. The lac operon is switched off when a protein called a(n) ______________________ is bound to the operator. 10. In eukaryotic gene regulation, proteins called ______________________ ______________________ help arrange RNA polymerases in the correct position on the promoter. 11. In eukaryotes, long segments of nucleotides with no coding information are called ______________________. 12. In eukaryotes, the portions of a gene that are actually translated into proteins are called ______________________. 13. Insertions, deletions and point mutations are types of ______________________ mutations. 14.
