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

ysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. lysosomal enzymes are synthesized in the endoplasmic reticulum (er), are transported to the golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label.

explanation:

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
