on Select all characteristics of proteins that are positive regulators of transcription Check All That Apply Positive regulators of transcription never need to associate with any other molecule to bind DNA. O Positive regulators help recruit ribosomes. O Positive regulatory proteins can affect only one operon. O Positive regulators often bind effectors before binding with DNA. O Activators regulate some degradative pathways. O Positive regulators help recruit RNA polymerase. Prey e to search

Why are proteins heat denatured prior to analysis in SDS-PAGE? Select all answers that apply. Denaturation of the protein is necessary so that proteins run proportionally to their size, based on the interaction of SDS with the unfolded protein. Heat is used to hydrolyze the peptide bonds of the protein. The heat step allows the proteins to unfold, enabling the protein chain to be coated with SDS molecules. Heat is used to hydrolyze disulfide bonds. QUESTION 2 1.5 points Saved...
