Chargaff's rule. states DNA of any species contains equal amounts of guanine and cytosine and also equal amounts of adenine and thymine. . This pattern is found in both strands of the DNA. . They were discovered by Austrian chemist Erwin Chargaff. A eukaryotic transcription initiation complex consists of RNA polymerase II, . five. general transcription factors (GTFs), and a 20-subunit complex called Mediator (or . Srb. /Med). The CTD of RNA polymerase II anchors Mediator to the polymerase. Mediator allows RNA polymerase II to communicate with transcriptional . .. The length of the transcription bubble is about 12 to 14 . bp. , but the length of the RNA–DNA hybrid within the bubble is only 8 to 9 . bp. . As the enzyme moves along the template, the DNA duplex reforms. RNA Polymerases of Eukaryotes. Since typical eukaryotic cells have 10 times as many genes as do bacteria, the whole process of transcription and its regulation is more complex. . Indeed, eukaryotes have multiple RNA polymerases, unlike bacteria which have just one. Typical .
