19 which eukaryotic polymerase would be most prevalent in...

A scientist has discovered a new eukaryotic gene. She wants to determine which RNA polymerase transcribes it, so she applies α-amanitin to a tissue culture of the cells and measures the amount of gene product produced. She finds that some gene product is produced, however it is less than the amount produced by a control group which received no α-amanitin. She concludes that which RNA polymerase transcribes this gene? Select One: a. I b. II c. III d. IV Based on the eukaryotic RNA polymerase (I, II, or III) that transcribes them, which of the following transcripts will be least affected by low levels of α-amanitin? Select one or more: a. pre-tRNAs b. pre-mRNA c. 5S rRNAs d. 18S rRNAs e. 28S rRNAs f. small nuclear RNAs The protein complex that removes and later replaces histones during eukaryotic transcription is called______.
