How are dna and rna polymerases different
WebTranscription uses one of the two exposed DNA strands as a template; this strand is called the template strand.The RNA product is complementary to the template strand and is almost identical to the other DNA strand, … WebIn comparison to prokaryotes, where only a single polymerase is required to bind with the DNA strands, eukaryotes require three different polymerases, along with an additional set of transcriptional factors (TFs) for transcription and translation. The three polymerases required are RNA polymerase I, RNA polymerase II and RNA polymerase III.
