WebEukaryotes require a minimum of seven transcription factors in order for RNA polymerase II (a eukaryote-specific RNA polymerase) to bind to a promoter. Transcription is tightly controlled in both bacteria and eukaryotes. Promoters are controlled by various DNA regulatory sequences including enhancers, boundary elements, insulators, and silencers. Web13 apr. 2024 · One exception is the addition of an N7-methylguanosine to the 5ʹ end of select eukaryotic RNAs transcribed by RNA polymerase II referred to as “m 7 G cap” 1.

WebTranscription in prokaryotes (and in eukaryotes) requires the DNA double helix to partially unwind in the region of mRNA synthesis. The region of unwinding is called a transcription bubble. Transcription always proceeds from the same DNA strand for each gene, which is called the template strand. WebRNA polymerase II transcribes eukaryotic genes that code for proteins. The assorted transcription factors bind to and recognize specific sequences on the DNA. These DNA …
