Problem: During transcription elongation, what is the function of DNA topoisomerases?A. identifying the region where termination will be taking place so that RNA polymerase can slow elongation before stoppingB. opening the DNA to form the transcription bubble for RNA polymerase to beginC. coiling the DNA after RNA polymerase has passed by so that it is ready for the next round of transcriptionD. removing positive DNA supercoils that are being produced by RNA polymeraseE. removing negative supercoiling so that the promoter region is available for sigma factor
