PPT-Transcription Chargaff's rule

Chargaffs 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. and Its Regulation.

The CTD of RNA polymerase II anchors Mediator to the polymerase. Mediator allows RNA polymerase II to communicate with transcriptional . 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 .
