Select which investigation is most appropriate to identify the roles of these molecules in transcription? A) an analysis of how molecule 1 copies itself to become molecule 2 B) an analysis of how molecule 2 acts a template to make molecule 1 C) an analysis of the number of nucleotides in both molecules 1 and 2 D) an analysis of how molecules 1 and 2 travel outside of the nucleus to the cytoplasm
