EUKARYOTIC TRANSCRIPTION: Eukaryotic transcription is different from prokaryotes transcription, eukaryotes transcription requires transcription binding factors ,enhancer along with RNA polymerase ,transcription factors are a protein which are essential for transcription but these are not the part of RNA polymerase, DNA template. These factors are bind at DNA template sequentially and then DNA polymerase bind and form a initiation complex. Basal transcription factor create a structure at the promoter, so RNA polymerase can easily recognise to promoter, in bacteria single RNA polymerase can transcribed the all type of RNA but in eukaryotes it requires different RNA polymerase for different RNA structure.

RNA Polymerase: The RNA polymerase of mitochondria and chloroplast are similar like bacteria. All eukaryotic RNA polymerases are multi subunit proteins which contain. Three different types of RNA polymerases are responsible for transcription (Table 28.2).
