PLEASE HELP ASAP Use the diagram representing the typical steps in gene expression and protein formation to respond:

All of the following help the cell regulate gene expression during Step 2 of protein formation except

general factors that are required for the RNA polymerase to bind to the promoter
repressors binding to the operator preventing the RNA polymerase from progressing
specialty factors binding to the RNA polymerase, altering its specificity
tRNA that binds to the RNA polymerase in the presence of complementary mRNA
