A class II gene is a type of gene that codes for a protein. Class II genes are transcribed by RNAP II.
Class II genes have a promoter that may contain a TATA box.
Basal transcription of class II genes requires the formation of a preinitiation complex.
They are transcribed by RNA polymerase II, include both intron and exon, and code for polypeptide.
