1. (3 pts) The following gel shows transcription of 3 different RNA's in the presence and absence of alpha- amanitin. The RNA are: 7SL RNA, 28S rRNA, and polyA RNA. Figure out which RNA is made by which RNA polymerase (I ll or III). 7SL RNA is made by: – 28S rRNA is made by: polyA RNA is made by: Which of these lanes represent which RNA? (you might have to google the expected sizes of some of these RNA's to figure out the answer.) transfection 0.3 a-amanitin (ug/ml) . A • B • C - genomic HDV RNA
