Quizplus · Accepted Answer

In eukaryotes, RNA polymerases I, II, and III recognize different types of promoters, not a single universal promoter or specific sequence mentioned in the options. RNA polymerase I transcribes rRNA genes, RNA polymerase II transcribes mRNA and some snRNA and miRNA genes, and RNA polymerase III transcribes tRNA and other small RNA genes. Each has distinct promoter requirements and associated factors, not a single common element as suggested in the options.
