- Gene Expression: 14) Look at the diagram: a) For each of the molecules in the diagram, identify what type of molecule they are, and label their ends (3',5',N,C). b) For each arrow, name the process and identify the major enzymes involved. c) Where do each of these activities take place in a bacterial cell? In a eukaryotic cell? Draw a picture if it helps you explain it.arrow_forwardDescribe the initiation of transcription listing all the transcription factors involved and their respective functions.arrow_forwardDefine mutation.
